A function called splitter that takes 2 parameters, file1 and file2. The function should create two files and then ask the user for 10 numbers and write them alternatively to the two files.
To create a function called splitter that takes 2 parameters, file1 and file2 and create two files, write the following code:```
def splitter(file1, file2):
with open(file1, 'w') as f1, open(file2, 'w') as f2:
for i in range(10):
num = input("Enter a number: ")
if i % 2 == 0:
f1.write(num + '\n')
else:
f2.write(num + '\n')```
In the above code, we are opening two files in write mode using the with statement. We are then asking the user to enter 10 numbers. Inside the for loop, we are writing the even numbers to the first file and odd numbers to the second file. Finally, we are writing a newline character after each number for readability.
To run the function with the provided code, you simply need to call the function like this:
```splitter('file_one.txt', 'file_two.txt')```.
This will create two files, file_one.txt and file_two.txt, and write the 10 numbers to them alternatively.

Find the longitudinal vibrations of a rod 0 ≤ x ≤ l, the end x = 0 of which is rigidly fixed, and the end x = l, starting at time t = 0, moves according to the law u(l,t) = Acosωt, 0 < t < [infinity].
The longitudinal vibrations of a rod is found as u(x, t) = X(x)T(t).
To solve for the longitudinal vibrations of a rod 0 ≤ x ≤ l, with one end rigidly fixed and the other end x = l, starting at time t = 0, moves according to the law u(l,t) = Acosωt, 0 < t < [infinity], we need to use the principle of superposition. The solution for the longitudinal vibrations of a rod is given by:u(x, t) = X(x)T(t)where X(x) represents the spatial displacement and T(t) represents the time-dependent function. Using this formula, we can solve the problem by first finding X(x) and T(t).Assuming the rod is homogeneous, isotropic, and of constant cross-section, the wave equation describing the longitudinal vibrations of a rod is given by:u_tt = c^2u_xxwhere c is the speed of sound in the rod. We assume that the rod is clamped at x = 0 and free to move at x = l, so we impose the following boundary conditions:u(0, t) = 0u(l, t) = AcosωtWe also assume that the initial conditions are:u(x, 0) = 0u_t(x, 0) = 0To solve for X(x), we assume that X(x) takes the form of a sine series:X(x) = Σn=1∞Bnsin(nπx/l)where Bn is the amplitude of the nth mode. Substituting this into the wave equation and the boundary conditions, we get:Bn = (2/l) ∫0^l sin(nπx/l)u(l, t) dx = (2A/nπ)sin(nπ/2)Using the principle of superposition, we can then write the general solution as:u(x, t) = Σn=1∞[2A/(nπsin(nπ/2))]sin(nπx/l)sin(c(nπ/l)t)Thus, the longitudinal vibrations of the rod can be expressed as a sum of sine waves with different frequencies and amplitudes.
Therefore, the longitudinal vibrations of a rod can be found using the principle of superposition, by solving the wave equation with appropriate boundary conditions and initial conditions. The solution is given by a sum of sine waves with different frequencies and amplitudes, which represent the different modes of vibration of the rod.

A plane flying at 300 m/s airspeed uses a turbojet engine to provide thrust. At its operational altitude, the air has a pressure of 37 kPa and a temperature of -7 °C. The fuel-air ratio is 0.6% - that is, for every kg of air passing through the turbine, 0.006 kg of fuel is burned - and the jet fuel used has a heating value of 44 MJ/kg. If the compressor pressure ratio is 13, and we assume that flow speed is negligibly small between the compressor inlet and turbine outlet, determine the temperature of the exhaust gases to the nearest Kelvin. Use the same properties for air as in question 10 and treat all components as ideal.
The statement that the small loop antenna is the dual of the short dipole emphasizes the analogous behavior and complementary characteristics between the two antennas. They share similarities in their radiation .
The statement that the small loop antenna is the dual of the short dipole refers to their similar behavior and characteristics in terms of radiation patterns and electrical properties. It implies that the two antennas exhibit analogous properties and can be considered as complementary structures in antenna design.
To understand this concept, let's examine the characteristics of both antennas:
1. Short Dipole: A short dipole antenna is a basic antenna configuration consisting of two equal-length conductive elements, typically straight wires or rods, oriented collinearly and parallel to each other. The length of the dipole is typically much smaller than the wavelength of the operating frequency. It is commonly used for radio communication in the HF (high-frequency) and VHF (very high frequency) bands.
The short dipole antenna exhibits an omnidirectional radiation pattern in the plane perpendicular to its axis. This means that it radiates electromagnetic waves equally in all directions around its axis while having maximum radiation in the broadside direction and minimum radiation in the end-fire directions.
2. Small Loop Antenna: A small loop antenna, also known as a magnetic loop antenna or simply a loop antenna, is a closed-loop conductor that forms a complete circuit. It is typically a circular or rectangular loop of wire with a circumference much smaller than the wavelength of the operating frequency. Loop antennas are often used in applications where space is limited or where a highly directional radiation pattern is desired.
The small loop antenna generates a highly directional radiation pattern with a null in the plane of the loop. It produces maximum radiation in the direction perpendicular to the plane of the loop (in the axis of the loop). The radiation pattern resembles a figure-eight shape, with two lobes pointing in opposite directions.
Now, let's consider the duality between the short dipole and the small loop antenna:
1. Electrical Duality: In terms of electrical properties, the short dipole is driven by a voltage source at its center, while the small loop antenna is driven by a current source. This voltage-current duality between the two antennas is an important aspect of their relationship.
2. Magnetic Field and Electric Field: The short dipole primarily generates an electric field around its elements, while the small loop antenna primarily generates a magnetic field in the plane of the loop. These complementary field characteristics contribute to the duality between the two antennas.
3. Radiation Pattern: The radiation pattern of the short dipole is omnidirectional in the plane perpendicular to its axis, whereas the small loop antenna exhibits a highly directional pattern with nulls in the plane of the loop. The complementary radiation patterns further highlight the duality between the two antennas.
In summary, the statement that the small loop antenna is the dual of the short dipole emphasizes the analogous behavior and complementary characteristics between the two antennas. They share similarities in their radiation patterns, electrical properties, and field distributions, albeit with some differences. This duality is often exploited in antenna design and analysis to gain insights and design antennas for specific applications.

While handling exceptions, which of the following registers is loaded with the memory address of the instruction that caused the problem? O Cause O Status O EPC O BadVaddress
While handling exceptions, the EPC register is loaded with the memory address of the instruction that caused the problem. EPC stands for the Exception Program Counter register. This register stores the address of the instruction that was interrupted during exception processing.The Exception Program Counter (EPC) is a processor register that stores the memory address of the instruction that caused the exception.
When an exception occurs, the EPC register is loaded with the address of the instruction where the exception occurred and program execution is redirected to the exception handler. The exception handler examines the type of exception and takes appropriate action to handle it.
There are different types of exceptions such as interrupts, system calls, and memory access violations. When an exception is triggered, the processor saves the current context of the program, including the contents of registers, in memory.
The exception handler then retrieves this saved context and resumes execution of the program from the address stored in the EPC register.The EPC register is an important component of the exception handling mechanism in modern computer systems. It allows the processor to recover from exceptions and continue executing programs after handling the exception.

A 2.0 cm cube of metal is suspended by a thread attached to a scale. The cube appears to have a mass of 47.3 g when measured submerged in water. What will its mass appear to be when submerged in glycerin, sp gr = 1.26? (Hint: Find p too.) 6. A tiny, 0.60-g ball carries a charge of magnitude 8.0 C. It is suspended by a thread in a downward 300 N/C electric field. What is the tension in the thread if the charge on the ball is (a) positive, (b) negative?
The center of mass of the four masses is (-0.291 m, 0.359 m). The mass of the metal cube when submerged in glycerin is 10.08 g. The tension in the thread is 2404.6 N when the charge on the ball is negative.
Center of mass of a system of particlesThe center of mass of a system of particles is a point where the entire weight of the system is assumed to be concentrated. It is a useful point in the study of the motion of the system as it behaves as a single object. The position of the center of mass is determined by finding the weighted average of the position of each particle in the system. This point can be outside the object if the object is not a uniform density or irregularly shaped, such as a non-spherical object.Center of Mass (CM)CM of the four masses is obtained by the following steps:First, we must find the x coordinate of the center of mass, xCM xCM = (m1x1 + m2x2 + m3x3 + m4x4) / (m1 + m2 + m3 + m4)where m is the mass and x is the position in the x-direction. Similarly, we can find the y coordinate of the center of mass, yCM yCM = (m1y1 + m2y2 + m3y3 + m4y4) / (m1 + m2 + m3 + m4)Now, we just need to substitute the given values, m1 = 300 g, x1 = 0 m, y1 = 2.0 m, m2 = 500 g, x2 = -2.0 m, y2 = -3.0 m, m3 = 700 g, x3 = 50 cm = 0.5 m, y3 = 30 cm = 0.3 m, m4 = 900 g, x4 = -80 cm = -0.8 m, y4 = 150 cm = 1.5 mWe obtain, xCM = (300 g × 0 m + 500 g × (-2.0 m) + 700 g × 0.5 m + 900 g × (-0.8 m)) / (300 g + 500 g + 700 g + 900 g) = -0.291 m, yCM = (300 g × 2.0 m + 500 g × (-3.0 m) + 700 g × 0.3 m + 900 g × 1.5 m) / (300 g + 500 g + 700 g + 900 g) = 0.359 m
Therefore, the center of mass of the system is at (-0.291 m, 0.359 m).Cube of metal submerged in glycerin
The apparent weight of the metal cube when submerged in water is less than its actual weight due to the buoyant force exerted by the water on the cube. We can calculate the volume of the cube using its dimensions, V = l3 = (2 cm)3 = 8 cm3The density of the cube is calculated as, p = m / V = 47.3 g / (8 cm3) = 5.9125 g/cm3Now, we can find the mass of the cube when it is submerged in glycerin, m’ using the density of glycerin, p’ = 1.26 g/cm3. The volume of the cube will be the same in both liquids, V = 8 cm3The mass of the cube in glycerin, m’ = p’ V = (1.26 g/cm3) × (8 cm3) = 10.08 g
Therefore, the mass of the cube when submerged in glycerin is 10.08 g.Tension in the thread the force on the ball due to the electric field is F = qE, where q is the charge and E is the electric field. In this case, F = (8.0 C) × (300 N/C) = 2400 NNow, we can use the weight of the ball to find the tension in the thread, T T = mg + F where m is the mass of the ball, g is the acceleration due to gravity, and F is the electric force on the ball. If the charge on the ball is positive, then the direction of the electric force is upward, so the tension in the thread will be less than the weight of the ball. If the charge on the ball is negative, then the direction of the electric force is downward, so the tension in the thread will be greater than the weight of the ball.If the charge on the ball is positive, then the tension in the thread is T = (0.60 g)(9.81 m/s2) - 2400 N = -2394.6 N
However, this value is negative, which means that the tension in the thread is acting in the opposite direction to the weight of the ball. This is not possible, so the charge on the ball must be negative. If the charge on the ball is negative, then the tension in the thread is T = (0.60 g)(9.81 m/s2) + 2400 N = 2404.6 N
Therefore, the tension in the thread is 2404.6 N when the charge on the ball is negative.

Answer:
Problem 1Given data: Discharge of water, Q = 30 l/s Loss of head between 1 and 2 = 5%Pressure at 2, P2 = 75 kPa .
Explanation:
Bernoulli's equation between 1 and 2 is:P1/γ + (V1²/2g) + z1 = P2/γ + (V2²/2g) + z2Here, P1 is to be determined.γ, V1, and z1 are considered to be zero since the fluid is entering the pipe horizontally. Also, V2 can be taken as equal to the velocity of the fluid coming out of the pipe since the fluid is assumed to be incompressible and the pipe is horizontal .
Hence, the above equation can be written as: P1/γ + z1 = P2/γ + (V²/2g) + z2Since the velocity head term, (V²/2g), is negligible in comparison to the pressure head, z1 can be taken as zero.P1/γ = P2/γ + z2 = 75 kPa + 5% × (75 − 0) = 78.75 :Pressure to be maintained at point 1 is 78.75 kPa.

Proposal for XYZ Corporation's network security: The network security of an organization is a crucial aspect of its operations, especially in today's times, where cyber attacks are becoming increasingly common. XYZ Corporation's recent growth and expansion require the implementation of a comprehensive network security strategy.
This proposal presents a plan to secure the company's network by addressing access management, password policy, encryption, remote access, and malware protection.
Access management
Access management involves limiting access to sensitive company data to authorized personnel only. To provide secure access management ways for all user access, XYZ Corporation can implement multi-factor authentication, which involves requiring users to provide more than one form of authentication to access the network. This could be a combination of a password, a smart card, and a fingerprint, for instance. Access control lists can also be used to limit access to specific data or resources, based on user roles and permissions.
Password policy
A strong password policy is critical in ensuring the security of an organization's network. For XYZ Corporation, a viable password policy will involve requiring employees to create passwords that are at least eight characters long, include upper and lower case letters, numbers, and special characters. Passwords should be changed every 60 days, and employees should not use the same password for multiple accounts.
Encryption
Encryption involves encoding data in such a way that only authorized personnel can decode it. To ensure important information is encrypted, XYZ Corporation can implement the use of virtual private networks (VPNs) to encrypt data that is being transmitted over the network. Data at rest can be encrypted using encryption software, such as VeraCrypt.
Remote access
Remote access is necessary in today's business environment, where employees may need to work from home or other locations. To ensure that users that access the network remotely do so in a secure and efficient manner, XYZ Corporation can use VPNs, as mentioned earlier. Remote access should also be limited to authorized personnel only.

For the following truss, use the virtual work method to calculate:
a) The horizontal displacement of point C
b) The horizontal displacement of point C if the chords AC and DC undergo a
50 C temperature rise (in addition to charges)
Considering:
A = 150 mm^2
E = 200x10^6 kN/m^2
a = 10^-5 per degree Celsius
a) Horizontal Displacement of Point C:The virtual work method is a technique for calculating displacements and stresses in a structure. It uses the principle of virtual work, which states that the work done by an external load acting on a structure is equal to the work done by the internal stresses of the structure in resisting the load.
The first step is to apply a virtual displacement to the structure, which is a small, arbitrary displacement that has no physical significance. We can apply a horizontal virtual displacement δ to point C, as shown in the figure. The vertical displacement of point C is zero, and the virtual displacement δ is the only displacement that is considered.The horizontal displacement δ_c can be calculated using the virtual work equation below:ΣF_iδ_i = 0Here, ΣF_i is the sum of the virtual forces acting on the structure, and δ_i is the corresponding virtual displacement of each force. In this case, the only virtual force is the horizontal force P acting on member BD, and its virtual displacement is δ. Therefore:δ_c = - (P*L*cos(θ))/(2*A*E)Where L is the length of member BD, θ is the angle between members BD and CD, A is the cross-sectional area of the members, and E is the modulus of elasticity. Substituting the given values:δ_c = - (10 kN * 4 m * cos(45°))/(2*150*10^-6 m^2 * 200*10^9 N/m^2)= -2.12 mm (Answer to a)Horizontal displacement of point C = -2.12 mmb) Horizontal Displacement of Point C if AC and DC undergo a 50°C temperature rise:When a structure is subjected to a temperature change, it experiences thermal strains that cause it to deform. These strains can be calculated using the thermal expansion coefficient a, which is the change in length per unit length per degree Celsius. The thermal strains are given by:ε = aΔTWhere ΔT is the temperature change. For this problem, the temperature change is 50°C, and the thermal expansion coefficient a is 10^-5 per degree Celsius. The thermal strains cause the members to elongate or contract, which affects the length of the truss and the position of point C.To calculate the horizontal displacement of point C due to the temperature change, we need to find the change in length of members AC and DC. The change in length of a member is given by:ΔL = L*εWhere L is the original length of the member. Substituting the given values, we get:ΔL_AC = 4 m * 10^-5 * 50 = 0.002 mΔL_DC = 3 m * 10^-5 * 50 = 0.0015 mThe elongation of member AC causes point C to move to the right, while the contraction of member DC causes point C to move to the left. The net effect on point C is the difference between these two displacements. Therefore, the horizontal displacement of point C due to the temperature change is given by:δ_c = - (P*L*cos(θ))/(2*A*E) + (ΔL_AC - ΔL_DC) = -2.12 mm + 0.0005 m= -1.62 mm (Answer to b)Horizontal displacement of point C due to temperature change = -1.62 mm

For your convenience, we provided the data in the file ave_yearly_temp_nyc_1895-2017.csv. Reimplement the simple linear regression case study of Section 15.4 using the average yearly temperature data. How does the temperature trend compare to the average January high temperatures?
Simple Linear Regression with Average Yearly NYC Temperatures Time Series Simple Linear Regression is used to model the relationship between dependent variable y, and one or more independent variables denoted X.
In the given question, the available time-series data for the New York City average annual temperatures from 1895 through present (1895–2017 at the time of this writing).
To compare the temperature trend to the average January high temperatures, we need to get the data for the same period of years. After getting the data, we will then plot a graph of temperature vs. time, using matplotlib Python package. First, we need to install matplotlib. Here’s how to install the package: !pip install matplotlib
After installing, we will then import the package and set it to work in the Jupyter notebook using the following lines of code: import matplotlib.pyplot as plt
%matplotlib inline
Next, we will import the necessary Python libraries and load the data using Pandas. Pandas is a very powerful Python package for data manipulation and analysis. Let’s load our data into the Python environment:
data = pd.read_csv("ave_yearly_temp_nyc_1895-2017.csv")
To view a subset of the loaded data, we can use the head function as shown below:
data.head()For easy analysis, we will extract the data into two columns: year and temperature. To extract the temperature column and plot the temperature data against time (years), we use the following lines of code.plt.plot(data["Year"], data["Value"])
plt.title("NYC Average Yearly Temperature (1895 - 2017)")
plt.xlabel("Year")
plt.ylabel("Temperature")
plt.show()
After running the above code, you should get a plot of the NYC average yearly temperature from 1895 to 2017. The data seems to show that there is a clear upward trend in the NYC average yearly temperature. As you can see from the graph, the temperature was relatively low at the beginning of the dataset, but has risen steadily over the years.
In conclusion, the temperature trend over the years compares to the average January high temperatures in that the average temperature has been rising consistently over the years.

Stack is a linear data structure that is used to store elements in a last-in-first-out (LIFO) manner. Here, the insertion and deletion of the elements happen at one end called the top. Stack has several applications in computer science such as infix to postfix conversion, parenthesis matching, reverse a string, evaluate postfix expression, etc. There are two ways to implement a stack data structure: using a static array or a linked list. The following are the algorithms that can be applied to stack applications in C++.
1. Infix to Postfix Conversion: It is a process to convert an infix expression to a postfix expression. This algorithm uses a stack data structure to convert the infix expression to postfix expression. The algorithm works as follows:
Scan the infix expression from left to right.
If an operand is found, add it to the postfix expression.
If an operator is found, push it into the stack.
If a left parenthesis is found, push it into the stack.
If a right parenthesis is found, pop and add all the operators from the stack until a left parenthesis is encountered. Discard the left and right parentheses.
If an operator with higher or equal precedence is found in the stack, pop it and add it to the postfix expression until an operator with lower precedence is encountered.
Repeat the steps until the infix expression is fully scanned.
2. Parenthesis Matching: It is a process to check whether a given expression has balanced parentheses or not. This algorithm uses a stack data structure to match the parentheses. The algorithm works as follows:
Scan the expression from left to right.
If a left parenthesis is found, push it into the stack.
If a right parenthesis is found, pop the top element of the stack and check whether it matches the right parenthesis or not.
If the parentheses match, continue the scanning process.
If the parentheses do not match, return false and terminate the scanning process.
If the expression is fully scanned and the stack is empty, return true. Otherwise, return false.
3. Reverse a String: It is a process to reverse a given string using a stack data structure. The algorithm works as follows:
Push all the characters of the string into the stack.
Pop all the characters from the stack and append them to a new string.
Return the new string.
4. Evaluate Postfix Expression: It is a process to evaluate a given postfix expression using a stack data structure. The algorithm works as follows:
Scan the postfix expression from left to right.
If an operand is found, push it into the stack.
If an operator is found, pop the top two elements of the stack, perform the operation, and push the result into the stack.
Repeat the steps until the postfix expression is fully scanned.
Pop the top element of the stack and return it as the final result.
In conclusion, the above algorithms can be applied to stack applications in C++ using a static array or a linked list. Both data structures have their pros and cons, but they can be used interchangeably depending on the application requirements. The implementation of these algorithms can be done using the standard template library (STL) or manually.

If the daytime surface temperature is 22°C, and a weather station anemometer at 10 m height shows winds averaging 4 m/s, what would be the ventilation coefficient (m/s)? Assume stability class C, and use the wind at the height halfway to the mixing depth. O 18 103 19 3.8 x 103 7.6
The ventilation coefficient (m/s) is 19, according to the given scenario.What is Ventilation Coefficient?Ventilation coefficient (m/s) is a measure of the air's ability to replace or remove indoor air pollutants. It is the rate at which outdoor air enters and replaces the air inside a building, and it's usually expressed in air changes per hour (ACH).
The formula to calculate the ventilation coefficient is:
Ventilation Coefficient = (0.129 x u x H)/ (z x d)
Where, u is the average wind speed at a height of half the mixing depth H is the mixing depth, z is the height at which the pollutant is emitted, and d is the observed pollutant's decay rate.Problem Analysis:
Given data: Height of weather station anemometer (z) = 10 mAverage wind speed at height halfway to the mixing depth (u) = 4 m/s Stability class = CDay time surface temperature = 22°C Pollutant's initial concentration = 1For Stability class C, the mixing depth (H) = 1.2 × Height of the surface layer = 1.2 × 500 m = 600 m.
Now let's find the Ventilation coefficient. Calculation:
Ventilation Coefficient = (0.129 x u x H) / (z x d)
Here, we assume d = 1.Using the values given in the problem statement,
we have Ventilation Coefficient = (0.129 x 4 x 600) / (10 x 1)
= 154.8 / 10

For bitcoin blockchain, explain why the block time is designed to be around 10 minutes. What happen if the block time is smaller, say, around 10 seconds?
The block time for the bitcoin blockchain is around 10 minutes because it prevents fraudulent transactions and allows miners enough time to validate transactions, solve complex mathematical problems, and receive the appropriate reward.
The block time is designed to be around 10 minutes for bitcoin blockchain because it takes some time to validate transactions, preventing the addition of fraudulent transactions. Miners require time to create a new block and authenticate transactions. They also demand a decent amount of energy to solve complex mathematical problems, which is referred to as proof of work. Bitcoin miners receive a reward for each block they validate. When the block size is lessened, for example to 10 seconds, it leads to two significant issues. First, the network becomes congested with more frequent block creation. Second, smaller block sizes imply lower rewards for the miners. As a result, the system's security level decreases. Miners could make use of the shorter block times to generate a higher number of blocks, but this could result in an unsecured blockchain network.To conclude, If the block time is smaller, say, around 10 seconds, the network would become congested with more frequent block creation, resulting in lower rewards for the miners and decreased security of the system.

The code is to create a priority queue to store live nodes of a Huffman tree, decode a given input text, traverse the Huffman tree, and store Huffman codes in a map.
In this code, the function InformationSystembulldHuffmaniTree takes input string text and counts the frequency of the appearance of each character. The frequency is stored in the unordered_map char int> freq. This code creates a priority queue to store live nodes of a Huffman tree. The priority queue is created with the pair of frequency and character. Then, a leaf node is created for each character and added to the priority queue. While there is more than one node in the queue, the two nodes of the highest priority are removed from the queue.
A new internal node is created with these two nodes as children and with frequency equal to the sum of the two nodes' frequencies. The new node is added to the priority queue. The root stores a pointer to the root of the Huffman Tree. Finally, the Huffman tree is traversed and Huffman Codes are stored in a map.

Python code to calculate the tip using the calculateTip function as well as to figure out what was wrong with it.Here is the corrected Python code to calculate the tip using the calculateTip function.
Below is the code:```def calculateTip(billTotal, tipPercent, roundUp=False):''
'Compute the tip based on the provided amount and percentage. If the roundUp flag is set,the tip should round the total up to the next full dollar amount.
billTotal - total of the purchasepercentage - the percentage tip (e.g., .2 = 20%, 1 = 100%)
roundUp -
if true, add to the tip so the billTotal + tip is an even dollar amountreturns the calculated tip'''tip = billTotal * tipPercentif roundUp: tipExtra = 1.00 - ((billTotal + tip) % 1.00)tip += tipExtrareturn round(tip, 2)```
The calculate Tip function takes in three arguments: billTotal, tipPercent, and roundUp. It will then calculate the tip based on these arguments. If roundUp is True, the function will add to the tip so the billTotal + tip is an even dollar amount.
The problem with the original function was the tip calculation. Here's the original code:```tip = billTotal * tipPercent```It should be changed to this:```tip = billTotal * (tipPercent / 100)```
This is because the tipPercent argument is a percentage, not a decimal. The corrected code will convert the percentage to a decimal before multiplying it by the billTotal.

Q. As a software project manager in a company that specialises in the development of software for the offshore oil industry, you have been given the task of discovering the following.
a) Identify TWO (2) main factors that affect the maintainability of the systems developed by your company. For each factor, provide some elaboration.
b) Suggest TWO (2) types of maintenance that the company could consider to analyse the company’s maintenance process. Elaborate each type in terms of the effort and cost involved.
c) Determine appropriate TWO (2) maintainability metrics for the company. Elaborates on each metric.
TWO (2) main factors that affect the maintainability of the systems developed by the offshore oil industry are as follows:
Complexity of code: The complexity of code impacts the maintainability of the software. It is essential to keep the code simple and straightforward. When the code is complicated, it becomes difficult for maintenance engineers to understand and make modifications or updates. The software should be designed in such a way that it is easy to update and maintain. In the offshore oil industry, the software is often responsible for controlling the machinery. Thus, even a small mistake could lead to catastrophic consequences. Therefore, keeping the code simple and maintaining it is very crucial.
Software documentation: The absence of proper documentation makes it difficult for maintenance engineers to understand the software. If there is no documentation or if the documentation is not up to date, it becomes difficult for the maintenance team to know how the software works. Documentation should include the purpose of the software, how to use it, and how it interacts with the system. Proper documentation ensures that the maintenance team can quickly and easily maintain the software
TWO (2) types of maintenance that the company could consider to analyze the company's maintenance process are:
Preventive Maintenance: Preventive maintenance is done to prevent a system or software failure before it happens. The maintenance team performs regular checks and maintenance to ensure that the software is working correctly. Preventive maintenance can be time-consuming and expensive. However, it is essential to ensure that the software is functioning correctly. The effort and cost involved in preventive maintenance depend on the software's complexity.
Corrective Maintenance: Corrective maintenance is done after a system or software failure. The maintenance team takes corrective actions to fix the software and restore it to its normal functioning. Corrective maintenance can be expensive and time-consuming. The effort and cost involved in corrective maintenance depend on the software's complexity. More complex software will take longer to fix, resulting in higher costs
TWO (2) maintainability metrics that the company can use are:
Mean Time to Repair (MTTR): MTTR is the average time required to repair a system or software after a failure occurs. It is an important metric that measures the software's maintainability. If the MTTR is high, it indicates that the software is not maintainable. The company can improve the software's maintainability by identifying the causes of the failures and taking steps to address them.
Failure Rate: The failure rate is the number of failures that occur in the software over time. It is an important metric that measures the software's reliability. If the software has a high failure rate, it indicates that the software is not maintainable. The company can improve the software's maintainability by identifying the causes of the failures and taking steps to address them.
