Suppose that class OrderList has a private attribute double cost[100] which hold the cost of all ordered items, and a private attributes int num_of_items which hold the number of items ordered. For example, if num_of_items is 5, then cost[0], cost[1], ..., cost[4] hold the cost of these 5 items. Implement the member function named total_cost which returns the total cost of this OrderList.
Answer:
OrderList.java
public class OrderList { private double cost[]; private int num_of_items; public OrderList(){ cost = new double[100]; } public double total_cost(){ double total = 0; for(int i=0; i < num_of_items; i++){ total += cost[i]; } return total; } }Main.java
public class Main { public static void main(String[] args) { OrderList sample = new OrderList(); double totalCost = sample.total_cost(); } }Explanation:
Firstly, define a class OrderList with two private attributes, cost and num_of_items (Line 1-3). In the constructor, initialize the cost attribute with a double type array with size 100. Next, create another method total_cost() to calculate the total cost of items (Line 9-15). To implement the total_cost member function, create an OrderList instance and use that instance to call the total_cost() and assign it to totalCost variable.
You acquire a network vulnerability-scanning tool and try it out on a network address segment belonging to people at your university of business. The scanner identifies one computer named Prince Hal that has many serious vulnerabilities. You deduce to whom the machine belongs. Explain the ethical implication of:________.
a. telling the owner what you have found,
b. telling you local administrator or security officer what you have found
c. exploiting one of the relatively minor vulnerabilities to show the owner how serious the exposure is
d. exploiting a relatively minor vulnerability as a prank without telling the owner,
e. telling the owner what you have found and the demanding money for details on the vulnerabilities
f. using one of the vulnerabilities to acquire control of the machine, downloading and installing patches and changing settings to address all the vulnerabilities, and never telling anyone what you have done.
Answer and Explanation:
The speculates on either the morality of transmitting vulnerabilities to an individual over all the internet. The node is a very possible target of a criminal charge, these are highly recommended in terms of the problem not just ethical.The question argues the etiquette of telling a compromised network infrastructure to something like a domain admins or security guard. Throughout this case the primary admin issue is power. Informing individuals about both the potential problem is prudent or legal, which is also preferable to recommend the future course of action.The speculates on either the moral values of leveraging the infrastructure for a mild vulnerability. This same proprietor including its node is truly likely to be victims of a prospective infringement, and therefore it is advantageous to notify him including its problem that the equitable access is considered to become an ethical manipulate susceptibility for possessor data as well as potential threats to understanding.The theories a small flaw throughout the channel's ethics. The device's leader is the likely guilty party of even a future offense to notify him of both the actual problem. The law is ridiculous as well as comparable to trying to hack without permission vulnerability it's immoral vulnerability.The content upon the ethical principles of manipulating the channel's small susceptibility. The device's owner seems to be the likely casualty of such a future offense to instruct him including its subject. As well as trying to sell him much farther documents socially responsible borders. It's the holder who has so far notified the weakness she perhaps she has just one option to obtain products and services. Having clear data on the sale still seems to be ethical.The issue argues mostly on ethics with repairing security flaws without channel assent. Although the controlled variable of the modules has been the true likely target of such a future infringement, exploiting susceptibility without permission is appropriate as well as unethical, this same objective being honorable as well as noble.(Find the number of days in a month) Write a program that prompts the user to enter the month and year and displays the number of days in the month.

Consider a load-balancing algorithm that ensures that each queue has approximately the same number of threads, independent of priority. How effectively would a priority-based scheduling algorithm handle this situation if one run queue had all high-priority threads and a second queue had all low-priority threads
Answer and Explanation:
Consider giving greater priority to both the queue contains the national priority comment section as well as, therefore, first method the thread throughout this queue.If the item from either the major priority queue becomes decoupled, if the balancing between some of the number of comments in some of these two queues becomes disrupted, instead decouple one thread from either the queue comprising the low-value thread as well as position that one in the queue with the highest - priority loop to match the number of connections in such 2 queues.Whenever a new thread arrives with some kind of proper description, a friendly interface could've been introduced to just the queue contains fewer threads to achieve stability.Therefore, the load-balancing requirements for keeping about the same number of threads would be retained and the meaningful matter of top priority thread would also be retained.
Based on the information given, it is important to give higher priority to the queue that contains the high priority thread.
Also, once an element from the high priority queue is dequeued, then dequeue one thread from the queue containing low priority thread and this will be enqueued into the queue having high priority thread in order to balance the number of threads.
Since the priority queue automatically adjusts the thread, hence the removal of the thread from one priority queue to another is not a problem.

Enter a formula in cell C9 using the PMT function to calculate the monthly payment on a loan using the assumptions listed in the Status Quo scenario. In the PMT formula, use C6 as the monthly interest rate (rate), C8 as the total number of payments (nper), and C4 as the loan amount (pv). Enter this formula in cell C9, and then copy the formula to the range D9:F9.
Answer:
=PMT(C6,C8,C4)
Put that in cell c9
Then use the lower right of the cell to drag it from D9:F9
In this exercise we have to use excel knowledge, so we have to:
=PMT(C6,C8,C4) in the cell C9 and extended to D9:F9
How is PMT calculated in Excel?PMT, one of the financial functions, calculates the payment for a loan based on constant payments and a constant interest rate. Use the Excel Formula Coach to figure out a monthly loan payment.
For this we need to put the form as:
=PMT(C6,C8,C4)

What are the best data structures to create the following items? And why?
1. Designing a Card Game with 52 cards.
2. Online shopping cart (Amazon, eBay, Walmart, Cosco, Safeway, ...)
3. Online waiting list (De Anza College class waiting list, ...)
4. Online Tickets (Flight tickets, concert tickets, ...)
Answer:
The best structures to create the following items are
ARRAYHASHMAPS QUEUE SORTED LINK LISTSExplanation:
The best structures to create the following items are:
Array : for the storage of cards in a card game the best data structure to be used should be the Array data structure. this is because the size of the data ( 52 cards ) is known and using Array will help with the storing of the cards values in the Game.Hashmaps : Hashmap data structure should be implemented in online shopping cart this IS BECAUSE items can be easily added or removed from the cart therefore there is a need to map the Items ID or name to its actual database online waiting list are usually organised/arranged in a first-in-first-out order and this organization is best created using the queue data structure Sorted link lists is the best data structure used to create, store and manage online tickets. the sorted link data structure helps to manage insertions and deletions of tickets in large numbers and it also reduces the stress involved in searching through a large number of tickets by keeping the tickets in sorted listsWrite a class called Triangle that can be used to represent a triangle.

A. Digital encoding of information with the calculation being changed occasionally, particularly after the frameworks advisors have finished their employments, and the framework is being used.
Which can also mean; The money could be withdrawn form the ATM. preventive Control is password to be changed periodically and regularly.
B. Noise on the line might be causing line blunders, which can bring about information misfortune. Reverberation checks and equality checks can assist with recognizing and right such mistakes.
C. If information is being lost, reverberation checks and equality checks ought to likewise help; notwithstanding, the issue might be that an intruder is blocking messages and altering them. Message arrangement numbering will assist with deciding whether messages are being lost, and in the event that they are maybe a solicitation reaction strategy ought to be executed that makes it hard for gatecrashers to dodge.
D. In the event that messages are being postponed, a significant client request or other data could be missed. As in thing c, message arrangement numbering and solicitation reaction methods ought to be utilized.
E. Messages modified by intruders can have an extremely negative effect on client provider relations if orders are being changed. For this situation, information encryption is important to keep the gatecrasher from perusing and changing the information. Additionally, a message succession numbering strategy is important to ensure the message isn't erased.

Universal Containers (UC) is currently live with Sales Cloud and in the process of implementing Service Cloud. UC wants to create a sandbox to test its Service Cloud implementation with real Sales Cloud data. Which three Sandbox types can be used to accomplish this? Choose 3 answersA. Administrator SandboxB. Partial Copy SandboxC. Full SandboxD. Developer k Pro SandboxE. Test Sandbox
Answer:
B. Partial Copy Sandbox
C. Full Sandbox
D. Developer k Pro Sandbox
Explanation:
In this scenario Universal containers wants to implement a service cloud and test with real Sales Cloud data.
Service cloud is defined a system that allows automation of various customer service functions. It can listen to customers via different social media platforms and direct customers to agents that can solve their problems.
Sandbox is a testing environment that is isolated and allows for running of programs without affecting the application.
To test service cloud implementation with real data we use the following 3 sandboxes:
- Partial copy sandbox: copies only relevant data to test configurations with real data.
- Full Sandbox: makes a replica of data by copying all data such as attachments, metadata, and object records.
- Developer K pro sandbox: is used by developers to test software in an isolated environment and can use large data sets. It includes configuration data (metadata)

Identify a logical operation (along
with a corresponding mask) that, when
applied to an input string of 8 bits,
produces an output string of all 0s if and
only if the input string is 10000001.
Answer: Provided in the explanation section
Explanation:
The Question says;
Identify a logical operation (along
with a corresponding mask) that, when
applied to an input string of 8 bits,
produces an output string of all 0s if and
only if the input string is 10000001.
The Answer (Explanation):
XOR, exclusive OR only gives 1 when both the bits are different.
So, if we want to have all 0s, and the for input only 10000001, then we have only one operation which satisfies this condition - XOR 10000001. AND
with 00000000 would also give 0,
but it would give 0 with all the inputs, not just 10000001.

write the following function so that it returns the same result, but does
not increment the variable ptr. Your new program must not use anysquare brackets, but must use an integer variable to visit each double in the array. You may eliminate any unneeded variable.
double computeAverage(const double* scores, int nScores)
{
const double* ptr = scores;
double tot = 0;
while (ptr != scores + nScores)
{
tot += *ptr; } ptr++;
}
return tot/nScores;
b. Rewrite the following function so that it does not use any square brackets (not even in the parameter declarations) but does use the integervariable k. Do not use any of the functions such as strlen, strcpy, etc.
// This function searches through str for the character chr.
// If the chr is found, it returns a pointer into str where
// the character was first found, otherwise nullptr (not found).
const char* findTheChar(const char str[], char chr)
{
for(intk=0;str[k]!=0;k++)
if (str[k] == chr)
}
return &str[k];
return nullptr;
}

Advanced Sounds is engaging in a full upgrade of its Windows Server 2003 network to Windows Server 2008. The upgrade includes using Windows Server 2008 Active Directory. Advanced Sounds has pioneered many technological innovations and is very concerned about keeping its network and computer systems secure. Advanced Sounds Information Technology (IT) Department hires you to help them implement Windows Server 2008 Active Directory. Assume the following:
All email servers have been consolidated back in the New York City Complex.
Most all the other applications running on Windows Servers are distributed at all sixteen locations.
Each location at minimum has a file server, a print server and a local application server.
All locations have adequate Wide Area network connections with available capacity; 10 Mbps links
The New York location has enough network capacity to serve all 16 locations.
There are 500 people at the New Your City complex.
There are 200 people at the Quebec City location and 200 at the Montreal location.
There are 40-50 people at each outlet store.
Advanced Sounds IT Department has formed a small installation planning committee consisting of the IT server operations manager, two system programmers, the current Active Directory administrator, and you. After the first meeting they have asked you to prepare a small report to address the following questions:
A. What information is required as input to the initial installation involving Active Directory? a=
B. How many Active directory servers do you propose?
C. Where will the Active directory server(s) be located?
Answer:

Explanation:
Write an INSERT statement that adds these rows to the Invoice_Line_Items table:
invoice_sequence: 1 2
account_number: 160 527
line_item_amount: $180.23 $254.35
line_item_description: Hard drive Exchange Server update
Set the invoice_id column of these two rows to the invoice ID that was generated
by MySQL for the invoice you added in exercise 4.
Answer:
Insertion query for first row :
INSERT into Invoice_Line_Items (invoice_sequence, account_number, line_item_amount, line_item_description) Values (1, 160, '$180.23', "Hard drive Exchange");
Insertion query for second row :
INSERT into Invoice_Line_Items (invoice_sequence, account_number, line_item_amount, line_item_description) Values (2, 527, '$254.35', "Server update");
Explanation:
* In SQL for insertion query, we use INSERT keyword which comes under DML (Data manipulation Language).
* Statement is given below -
INSERT into Table_name (column1, column2, ....column N) Values (value1, value2, .....value N);
* With the use of INSERT query we can insert value in multiple rows at a same time in a table which reduces our work load.
CASE II AziTech is considering the design of a new CPU for its new model of computer systems for 2021. It is considering choosing between two (2) CPU (CPUA and CPUB) implementations based on their performance. Both CPU are expected to have the same instruction set architecture. CPUA has a clock cycle time of 60 ns and CPUB has a clock cycle time of 75 ns. The same number of a particular instruction type is expected to be executed on both CPUs in order to determine which CPU would executes more instructions. CPUA is able to execute 2MB of instructions in 5*106 clock cycles. CPUB executes the same number of instructions in 3*106 clock cycles. a) Using the MIPS performance metric, which of the two (2) CPU should be selected to be implemented in the new computer system. Justify your choice. b) Compute the execution time for both CPUs. Which CPU is faster?
Answer:
(a)The CPU B should be selected for the new computer as it has a low clock cycle time which implies that it will implement the process or quicker when compared to the CPU A.
(b) The CPU B is faster because it executes the same number of instruction in a lesser time than the CPU A .
Explanation:
Solution
(a)With regards to the MIPS performance metric the CPU B should be chosen for the new computer as it low clock cycle time which implies that it will implement the process or quicker when compared to the CPU A and when we look at the amount of process done by the system , the CPU B is faster when compared to other CPU and carries out same number of instruction in time.
The metric of response time for CPU B is lower than the CPU A and it has advantage over the other CPU and it has better amount as compared to CPU A, as CPU B is carrying out more execution is particular amount of time.
(b) The execution can be computed as follows:
Clock cycles taken for a program to finish * increased by the clock cycle time = the Clock cycles for a program * Clock cycle time
Thus
CPU A= 5*10^6 * 60*10^-9 →300*10^-3 →0.3 second (1 nano seconds =10^-9 second)
CPU B= 3 *10^6 * 75*10^-9 → 225*10^-3 → 0.225 second
Therefore,The CPU B is faster as it is executing the same number of instruction in a lesser time than the CPU A
Two of the most fundamental functions for dealing with interprocess communication are read() and write(). Consider the following otherwise valid C program:int r, pipeFDs[2];
char message[512];
pid_t spawnpid;
pipe(pipeFDs);
spawnpid = fork();
switch (spawnpid)
{
case 0:
close(pipeFDs[0]); // close the input file descriptor
write(pipeFDs[1], "hi process, this is the STUFF!!", 21);
break;
default:
close(pipeFDs[1]); // close output file descriptor
r = read(pipeFDs[0], message, sizeof(message));
printf("Message received from other: %s\n", message);
break;
}
Select each of the following answers that is correct. CAN BE MULTIPLE CHOICES...
(1) The read() call may block until data becomes available
(2) When the read() call returns, this one call will return all of the data that was sent through the pipe, which is different behavior than if this was a socket
(3) If the read() call blocks, the process will be suspended until data arrives
(4) The write() call will return before all of the data has been written, if the corresponding read() call blocks mid-transfer
(5) Pipes can fill, which will cause the write() call to block until the read() call is able to read data from the pipe
Answer: Provided in the explanation section
Explanation:
int r, pipeFDs[2];
char message[512];
pid_t spawnpid;
pipe(pipeFDs);
spawnpid = fork();
switch (spawnpid)
{
case 0:
close(pipeFDs[0]); // close the input file descriptor
write(pipeFDs[1], "hi process, this is the STUFF!!", 21);
break;
default:
close(pipeFDs[1]); // close output file descriptor
r = read(pipeFDs[0], message, sizeof(message));
printf("Message received from other: %s\n", message);
break;
}
Observation of the program:
The read() call may block until data becomes available If the read() call blocks, the process will be suspended until data arrives Pipes can fill, which will cause the write() call to block until the read() call is able to read data from the pipe⇒ Therefore,Option 1,3 and 5 correct
Cheers i hope this helped !!!
