Answer:
Following are the calling of the given question
public static void main(String[] args) // main function
{
int store; // variable declaration
store = sum(32,15,"san"); // Calling of sum()
System.out.println(" TheValue returned by sum() : "+store); // display
}
Explanation:
Following are the description of the above statement
Here is the name of function is sum() In the sum() function definition there are 3 parameter in there signature i.e two "int" type and 1 is "string" type .In the main function we declared the variable store i,e is used for storing the result of sum() it means it storing the result of value that is returning from the definition of sum() function .After that calling the function by there name and passing three parameter under it sum(32,15,"san"); and store in the "store" variable.Finally print the value by using system.out.println ().The Fast Freight Shipping Company charges the following rates for different package weights:
2 pounds or less: $1.50
over 2 pounds but not more than 6 pounds: $3.00
over 6 pounds but not more than 10 pounds: $4.00
over 10 pounds: $4.75
Write a program that asks the user to enter the weight of a package and then displays the shipping charges. The program should also do "Input Validation" that only takes positive input values and show a message "invalid input value!" otherwise.
Answer:
import java.util.Scanner;
public class ShippingCharge
{
static double wt_2=1.50;
static double wt_6=3;
static double wt_10=4;
static double wt_more=4.75;
static double charge;
static double weight;
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
do
{
System.out.print("Enter the weight of the package: ");
weight = sc.nextDouble();
if(weight<=0)
System.out.println("Invalid input value!");
}while(weight<=0);
if(weight<=2)
charge=wt_2;
else if(weight<=6 && weight>2)
charge=wt_6;
else if(weight<=10 && weight>6)
charge=wt_10;
else
charge=wt_more;
System.out.println("Shipping charges for the entered weight are $"+charge);
}
}
OUTPUT
Enter the weight of the package: 0
Invalid input value!
Enter the weight of the package: 4
Shipping charges for the entered weight are $3.0
Explanation:
1. The variables to hold all the shipping charges are declared as double and initialized.
static double wt_2=1.50;
static double wt_6=3;
static double wt_10=4;
static double wt_more=4.75;
2. The variable to hold the user input is declared as double.
static double charge;
static double weight;
3. The variable to hold the final shipping charge is also declared as double.
4. Inside main(), an object of Scanner class is created. This is not declared static since declared inside a static method, main().
Scanner sc = new Scanner(System.in);
5. Inside do-while loop, user input is taken until a valid value is entered.
6. Outside the loop, the final shipping charge is computed using multiple if-else statements.
7. The final shipping charge is then displayed to the user.
8. All the code is written inside class since java is a purely object-oriented language.
9. The object of the class is not created since only a single class is involved.
10. The class having the main() method is declared public.
11. The program is saved with the same name as that of the class having the main() method.
12. The program will be saved as ShippingCharge.java.
13. All the variables are declared as static since they are declared outside main(), at the class level.
Write a program that asks the user to enter either an "African" or a "European" swallow. The programâs behaviour should mimic the program below. If the user enters something øther than "African" or "European", the program shøuld insult the user like the example below.
Sample Output #1:
What kind of swallow?
African
Yes, it could grip it by the husk.
Sample Output #2:
What kind of swallow?
European
A five-ounce bird could not carry a one-pound coconut.
Sample Output #3:
What kind of swallow?
Spanish
You really are not fit to be a king.
Answer:
The programming language is not stater; However, I'll answer this question using C++.
This program does not use comments (See explanation)
See Attachment for program file
Program starts here
#include <iostream>
using namespace std;
int main()
{
string response;
cout<<"What kind of swallow?\n";
cin>>response;
for(int i =0; i<response.length();i++)
{
response[i]=toupper(response[i]);
}
if(response == "AFRICAN")
{
cout<<"Yes, it could grip it by the husk.";
}
else if(response == "EUROPEAN")
{
cout<<"A five-ounce bird could not carry a one-pound coconut.";
}
else
{
cout<<"You really are not fit to be a king.";
}
return 0;
}
Explanation:
string response; -> A string variable to hold user input is declared
cout<<"What kind of swallow?\n"; -> prompts user for input
cin>>response; -> user input is stored here
The following iteration converts user input to uppercase; so that the program will work for inputs like African, AFRICAN, AFriCAN, etc.
for(int i =0; i<response.length();i++)
{
response[i]=toupper(response[i]);
}
The following if statement prints "Yes, it could grip it by the husk." if user input is AFRICAN
if(response == "AFRICAN")
{
cout<<"Yes, it could grip it by the husk.";
}
Otherwise, if user input is EUROPEAN, it prints; "A five-ounce bird could not carry a one-pound coconut."
else if(response == "EUROPEAN")
{
cout<<"A five-ounce bird could not carry a one-pound coconut.";
}
Lastly; for every inputs different from AFRICAN and EUROPEAN, the program displays "You really are not fit to be a king."
else
{
cout<<"You really are not fit to be a king.";
}

Given main(), define the Team class (in file Team.java). For class method getWinPercentage(), the formula is:teamWins / (teamWins + teamLosses)Note: Use casting to prevent integer division.Ex: If the input is:Ravens133 where Ravens is the team's name, 13 is number of team wins, and 3 is the number of team losses, the output is:Congratulations, Team Ravens has a winning average!If the input is Angels 80 82, the output is:Team Angels has a losing average.Here is class WinningTeam:import java.util.Scanner;public class WinningTeam {public static void main(String[] args) {Scanner scnr = new Scanner(System.in);Team team = new Team();String name = scnr.next();int wins = scnr.nextInt();int losses = scnr.nextInt();team.setTeamName(name);team.setTeamWins(wins);team.setTeamLosses(losses);if (team.getWinPercentage() >= 0.5) {System.out.println("Congratulations, Team " + team.getTeamName() +" has a winning average!");}else {System.out.println("Team " + team.getTeamName() +" has a losing average.");}}}
Answer:
Explanation:
public class Team {
private String teamName;
private int teamWins;
private int teamLosses;
public String getTeamName() {
return teamName;
}
public void setTeamName(String teamName) {
this.teamName = teamName;
}
public int getTeamWins() {
return teamWins;
}
public void setTeamWins(int teamWins) {
this.teamWins = teamWins;

Explanation:
During an investigation of a cybercrime, the law enforcement officers came across a computer that had the hard drive encrypted. Chose the best course of action they should take to access the data on that drive.
a. Use image filtering techniques to see what's behing the encrypted files.
b. Try to convince the owner of the computer to give you to decryption key/password.
c. Identify the encryption algorithm and attempt a brute force attack to get access to the file.
d. Disconnect the hard drive from power so the encryption key can be exposed on the next power up.
e. Try to copy the drive bit by bit so you can see the files in each directory.
Answer:
b. Try to convince the owner of the computer to give you to decryption key/password.
Explanation:
Encrypted hard drives have maximum security and high data protection. to access them you need to enter a password to unlock them.
The image filtering technique is a method that serves to selectively highlight information contained in an image, for which it does not work.
The encryption algorithm is a component used for the security of electronic data transport, not to access data on an encrypted hard drive.
The encryption key is used in encryption algorithms to transform a message and cannot be exposed by disconnecting the hard drive from its power source.
Write a Java program that reads from the user four grades between 0 and 100. The program the, on separate ines, prints out the entered grades followed by the highest grade, lowest grade, and averages of all four grades. Make sure to properly label your output. Use escape characters to line up the outputs after the labels.
Answer:
import java.util.*;
public class Grade {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
double[] grades = new double[4];
for (int i=0; i<4; i++){
System.out.print("Enter a grade: ");
grades[i] = input.nextDouble();
}
double lowest = grades[0];
double highest = grades[0];
double total = 0;
for (int i=0; i<4; i++){
System.out.println("Grade " + (i+1) + " is: " + grades[i]);
if(grades[i] >= highest)
highest = grades[i];
if(grades[i] <= lowest)
lowest = grades[i];
total += grades[i];
}
double average = total/4;
System.out.println("The highest grade is: " + highest);
System.out.println("The lowest grade is: " + lowest);
System.out.println("The average is: " + average);
}
}
Explanation:
Ask the user for the grades and put them in the grades array using a for loop
Create another for loop. Inside the loop, print the grades. Find highest and lowest grades in the grades array using if-structure. Also, add each grade to the total.
When the loop is done, calculate the average, divide the total by 4.
Print the highest grade, lowest grade and average.

Explanation:
Write a loop that sets each array element to the sum of itself and the next element, except for the last element which stays the same. Be careful not to index beyond the last element. Ex:
Initial scores: 10, 20, 30, 40
Scores after the loop: 30, 50, 70, 40
The first element is 30 or 10 + 20, the second element is 50 or 20 + 30, and the third element is 70 or 30 + 40. The last element remains the same.
SAMPLE OUTPUT:
#include
int main(void) {
const int SCORES_SIZE = 4;
int bonusScores[SCORES_SIZE];
int i = 0;
bonusScores[0] = 10;
bonusScores[1] = 20;
bonusScores[2] = 30;
bonusScores[3] = 40;
/* Your solution goes here */
for (i = 0; i < SCORES_SIZE; ++i) {
printf("%d ", bonusScores[i]);
}
printf("\n");
return 0;
}
Answer:
Replace /* Your solution goes here */ with the following lines of code
for(i = 0;i<SCORES_SIZE-1;i++)
{
bonusScores[i]+=bonusScores[i+1];
}
Explanation:
The above iteration starts from the index element (element at 0) and stops at the second to the last element (last - 1).
Using an iterative variable, i
It adds the current element (element at i) with the next element; element at i + 1.
The full code becomes
#include<iostream>
using namespace std;
int main(void) {
const int SCORES_SIZE = 4;
int bonusScores[SCORES_SIZE];
int i = 0;
bonusScores[0] = 10;
bonusScores[1] = 20;
bonusScores[2] = 30;
bonusScores[3] = 40;
for(i = 0;i<SCORES_SIZE-1;i++)
{
bonusScores[i]+=bonusScores[i+1];
}
/* Your solution goes here */
for (i = 0; i < SCORES_SIZE; ++i) {
printf("%d ", bonusScores[i]);
}
printf("\n");
return 0;
}
See attachment for .cpp file
Answer:int main() {
const int SCORES_SIZE = 4;
int bonusScores[SCORES_SIZE];
int i;
for (i = 0; i < SCORES_SIZE; ++i) {
cin >> bonusScores[i];
}
for (i = 0; i < SCORES_SIZE-1; ++i){
bonusScores[i] += bonusScores[i+1];
}
for (i = 0; i < SCORES_SIZE; ++i) {
cout << bonusScores[i] << " ";
}
cout << endl;
return 0;
}
Explanation: SCORES_SIZE -1 will prevent the for loop from going past the last value in the array. bonusScores[i] += will add the value of bonusScores[i+1] to the original bonusScores[i].
for example, i = 1; 1 < SCORES_SIZE - 1 ; bonusScores[1] += bonusScores[1+1} becomes{ bonusScores[1] + bonusScores{2];

textBox5.Text = "";
textBox6.Text = "";
textBox7.Text = "";
}
private void button8_Click(object sender, EventArgs e)
{
Close();
}
}
}
Explanation:
1. The integer variables are declared for total eggs, number of dozens and number of eggs.
2. The input of each text box is converted into integer by using the Convert.ToInt32() method on the value of that particular text box.
3. All the inputs are added and the sum is assigned to variable, total.
4. The number of dozens are obtained by dividing total by 12 and assigning the value to the variable, dozen.
5. The number of extra eggs are obtained by taking the modulus of total and 12 and the value is assigned to the variable, eggs.
6. The integer values in the variables, dozen and eggs, are converted into string using the ToString() function with that particular value.
dozen.ToString();
eggs.ToString();
7. The text boxes are assigned the respective values of dozens and number of eggs.
textBox6.Text = dozen.ToString();
textBox7.Text = eggs.ToString();
8. Two additional buttons, clear and exit, are also added.
9. The clear button erases the contents of all the text boxes. The Text property of each textbox is set to “” thereby clearing all the text fields.
10. The exit button closes the application using Close() function.
11. The program is made in visual studio and the output is attached.
Write a Python program that can compare the unit (perlb) cost of sugar sold in packages with different weights and prices. The program prompts the user to enter the weight and price of package 1, then does the same for package 2, and displays the results to indicate sugar in which package has a better price. It is assumed that the weight of all packages is measured in lb. The program should check to be sure that both the inputs of weight and price are both positive values.
Answer:
This program is written using python
It uses less comments (See explanation section for more explanation)
Also, see attachments for proper view of the source code
Program starts here
#Prompt user for price of package 1
price1 = int(input("Enter Price 1: "))
while(price1 <= 0):
price1 = int(input("Enter Price 1: "))
#Prompt user for weight of package 1
weight1 = int(input("Enter Weight 1: "))
while(weight1 <= 0):
weight1 = int(input("Enter Weight 1: "))
#Calculate Unit of Package 1
unit1 = float(price1/weight1)
print("Unit cost of Package 1: "+str(unit1))
#Prompt user for price of package 2
price2 = int(input("Enter Price 2: "))
while(price2 <= 0):
price2 = int(input("Enter Price 2: "))
#Prompt user for weight of package 2
weight2 = int(input("Enter Weight 2: "))
while(weight2 <= 0):
weight2 = int(input("Enter Weight 2: "))
#Calculate Unit of Package 2
unit2 = float(price2/weight2)
print("Unit cost of Package 2: "+str(unit2))
#Compare units
if unit1 > unit2:
print("Package 1 has a better price")
elif unit1 == unit2:
print("Both Packages have the same price")
else:
print("Package 2 has a better price")
Explanation:
price1 = int(input("Enter Price 1: ")) -> This line prompts the user for price of package 1
The following while statement is executed until user inputs a value greater than 1 for price
while(price1 <= 0):
price1 = int(input("Enter Price 1: "))
weight1 = int(input("Enter Weight 1: ")) -> This line prompts the user for weight of package 1
The following while statement is executed until user inputs a value greater than 1 for weight
while(weight1 <= 0):
weight1 = int(input("Enter Weight 1: "))
unit1 = float(price1/weight1) -> This line calculates the unit cost (per weight) of package 1
print("Unit cost of Package 1: "+str(unit1)) -> The unit cost of package 1 is printed using this print statement
price2 = int(input("Enter Price 2: ")) -> This line prompts the user for price of package 2
The following while statement is executed until user inputs a value greater than 1 for price
while(price2 <= 0):
price2 = int(input("Enter Price 2: "))
weight2 = int(input("Enter Weight 2: ")) -> This line prompts the user for weight of package 2
The following while statement is executed until user inputs a value greater than 1 for weight
while(weight2 <= 0):
weight2 = int(input("Enter Weight 2: "))
unit2 = float(price2/weight) -> This line calculates the unit cost (per weight) of package 2
print("Unit cost of Package 2: "+str(unit2)) -> The unit cost of package 2 is printed using this print statement
The following if statements compares and prints which package has a better unit cost
If unit cost of package 1 is greater than that of package 2, then package 1 has a better priceIf unit cost of both packages are equal then they both have the same priceIf unit cost of package 2 is greater than that of package 1, then package 2 has a better priceif unit1 > unit2:
print("Package 1 has a better price")
elif unit1 == unit2:
print("Both Packages have the same price")
else:
print("Package 2 has a better price")

Explanation:
Assume passwords are selected from four character combinations of 26 lower case alphabetic characters. Assume an adversary is able to attempt passwords at a rate of 1 per second. Assuming feedback to the adversary flagging an error as each incorrect character is entered, what is the expected time to discover the correct password
Answer:
Given:
Passwords are selected from 4 characters.
Character combinations are 26 lower case alphabetic characters.
Passwords attempts by adversary is at rate of 1 second.
To find:
Expected time to discover the correct password
Explanation:
Solution:
4 character combinations of 26 alphabetic characters at the rate of one attempt at every 1 second = 26 * 4 = 104
So 104 seconds is the time to discover the correct password. However this is the worst case scenario when adversary has to go through every possible combination. An average time or expected time to discover the correct password is:
13 * 4 = 52
You can also write it as 104 / 2 = 52 to discover the correct password. This is when at least half of the password attempts seem to be correct.
Create a program that asks the user to enter grade scores. Use a loop to request each score and add it to a total. Continue accepting scores until the user enters a negative value. Finally, calculate and display the average for the entered scores.
Answer:
total = 0
count = 0
while(True):
grade = float(input("Enter a grade: "))
if grade < 0:
break
else:
total += grade
count += 1
average = total/count
print("The average is: " + str(average))
Explanation:
*The code is in Python.
Initialize the total and count as 0
Create a while loop that iterates until a specific condition is met inside the loop
Inside the loop, ask the user to enter a grade. If the grade is smaller than 0, stop the loop. Otherwise, add the grade to the total and increment the count by 1.
When the loop is done, calculate the average, divide the total by count, and print it
a. A programmer wrote a software delay loop that counts the variable (unsigned int counter) from 0 up to 40,000 to create a small delay. If the user wishes to double the delay, can they simply increase the upperbound to 80,000?
b. If the code contains a delay loop and we noticed that no delay is being created at run-time. What should we suspect during debugging?
Answer:
Explanation:
The objective here is to determine if the programmer can simply increase the upperbound to 80,000.
Of course Yes, The programmer can simply increase the delay by doubling the upperbound by 80000. The representation can be illustrated as:
( int : i = 0; i < 40,000; i ++ )
{
// delay code
}
Which can be modified as:
( int : i = 0; i < 80,000; i ++ )
{
// delay code
}
b) If the code contains a delay loop and we noticed that no delay is being created at run-time. What should we suspect during debugging?
Assuming there is no delay being created at the run-time,
The code is illustrated as:
For ( int : i = 0 ; i < 0 ; i ++ )
{
// delay code which wont
//execute since code delay is zero
}
we ought to check whether the loop is being satisfied or not. At the Initial value of loop variable, is there any break or exit statement is being executed in between loop. Thus, the aforementioned delay loop wont be executed since the loop wont be executed for any value of i.
Can you please at least give me some part of the code. At least how to start it in C++. Thank you!
Project 5: You will design and implement various classes and write a program to manage one of the following a bank, a hospital, a library, a business, an organization, etc.) The program must do the following:
1. Allow the initialization of the different attributes of the objects from the keyboard.
2. Allow the initialization of the different attributes from a file
3. Perform calculations on one (or more) of the attributes (e.g. calculateInterest, generateHospitalBill, calculateCheckedBooks, etc.)
4. Output a report of all objects created. The report called for by requirement 4 should output all information about each object. You will need to take advantage of the capabilities of C++ classes, inheritance and overriding.
Program Design:
1. Create at least one base class. All data members have to be private. Your main function and any function that it calls should use the member functions of this class for all transactions.
2. Create at least two derived class of the base class described in the previous point.
3. The program will maintain arrays of objects that interacts with each other to manage the designated establishment (bank, hospital, library, etc.). Please do not use anything more sophisticated than an array.
4. Keep the program simple. I am interested in whether you can demonstrate basic competence in the use of classes, inheritance, and good design.
5. All data members in the classes must be private. This is to assure that you use the C++ capabilities that this assignment is all about. Do not use any global variables.
6. When the user decides to quit the updated information is saved back to the secondary storage to give the user the option to either start fresh or continue where he/she left off at the beginning of the next execution
Answer:
Explanation:
The objective of this question is to compute a program that involve using a C++ code for designing and implementing a Bank Account Management Simulator with integrated file storage for saving details to secondary storage.
When writing this code I notice the words are more than 5000 maximum number of characters the text editor can contain, so i created a word document for it. The attached file to the word document can be found below.
Write a function called unzip that takes as parameter a sequence (list or tuple) called seq of tuples with two elements. The function must return a tuple where the first element is a list with the first members of the seq tuple and the second element is a list with the second members of the seq tuple.
This example clarifies what is required:
Ist =[(1, "one"), (2, "two"), (3, "three")]
tup= unzip(Lst) lst tup
print(tup)
#prints ([1, 2, 3], ['one', two','three'7)
Answer:
Here is the function unzip:
def unzip(lst):
result= zip(*lst)
return list(result)
The complete program in Python is given below:
def unzip(lst):
result= zip(*lst)
return list(result)
lst =[(1, "one"), (2, "two"), (3, "three")]
tup= unzip(lst)
print(tup)
Explanation:
Here zip() function is used in the unzip function. The return type of zip() function is a zip object. This means the function returns the iterator of tuples. This function can be used as its own inverse by using the * operator.
If you do not want to use zip() function then the above program can also be implemented as following which uses a for loop for elements in the given list (lst). This can make a pair of lists (2 tuple) instead of list of tuples:
def unzip(lst):
output = ([ a for a,b in lst ], [ b for a,b in lst ])
return output
lst =[(1, "one"), (2, "two"), (3, "three")]
tup= unzip(lst)
print(tup)
The programs along with their output are attached.
Consider a recurrent neural network that listens to a audio speech sample, and classifies it according to whose voice it is. What network architecture is the best fit for this problem
Answer:
Many-to-one (multiple inputs, single output)
Explanation:
Solution
In the case of a recurrent neural network that listens to a audio speech sample, and classifies it according to whose voice it is, the RNN will listen to the audio and will give result by doing classification.
There will be a single output, for the classified or say identified person.
The RNN will take a stream of input as the input is a audio speech sample.
Therefore, there will be multiple inputs to the RNN and a single output, making the best fit Architecture to be of type Many-to-one(multiple inputs, single output).
It's inventiveness, uncertainty futuristic ideas typically deal with science and technology.what is it?
Answer:
Engineering and Science
Explanation:
In this assignment you'll write a program that encrypts the alphabetic letters in a file using the Hill cipher where the Hill matrix can be any size from 2 x 2 up to 9 x 9. The program can be written using one of the following: C, C++, or Java. Your program will take two command line parameters containing the names of the file storing the encryption key and the file to be encrypted. The program must generate output to the console (terminal) screen as specified below.Command Line Parameters1. Your program compile and run from the command line.2. The program executable must be named "hillcipher" (all lowercase, no spaces or file extension).3. Input the required file names as command line parameters. Your program may NOT prompt the user to enter the file names. The first parameter must be the name of the encryption key file, as described below. The second parameter must be the name of the file to be encrypted, as also described below. The sample run command near the end of this document contains an example of how the parameters will be entered.4. Your program should open the two files, echo the input to the screen, make the necessary calculations, and then output the ciphertext to the console (terminal) screen in the format described below.Note: If the plaintext file to be encrypted doesn't have the proper number of alphabetic characters, pad the last block as necessary with the letter 'X'. It is necessary for us to do this so we can know what outputs to expect for our test inputs.

A vSphere Administrator is receiving complaints a database VM is experiencing performance issues. The VM is a member of the high priority resource pool and the cluster has not experienced contention.
Which condition should be checked to address immediate performance concerns?
A. VM snapshots
B. VMFS version
C. Resource Pool share value
D. Configured CPU shares
Answer:
C. Resource Pool share value.
Explanation:
The vSphere is a term used to describe the VMware’s virtualization cloud platform. The vSphere comprises of the following, vCenter Server, ESXi, Virtual Machine File System (VMFS) and vCenter Client.
If a vSphere Administrator receive complaints that a database Virtual Machine (VM) is experiencing performance issues and the Virtual Machine (VM) is a member of the high priority resource pool and the cluster has not experienced contention.
In order to address immediate performance concerns, the vSphere Administrator should check the Resource Pool share value.
VMware resource pool refers to the aggregated central processing unit and memory allocated to a Virtual Machine (VM) for flexible management of the resources.
Also, the vSphere Administrator should install VMware tools to check which processes are having high CPU usage by using vimtop, as well as checking if vCenter Server is swapping.

What’s the best way to figure out what wires what and goes where?
Write a program in python that can compare the unit (perlb) cost of sugar sold in packages with different weights and prices. The program prompts the user to enter the weight and price of package 1, then does the same for package 2, and displays the results to indicate sugar in which package has a better price. It is assumed that the weight of all packages is measured in lb. The program should check to be sure that both the inputs of weight and price are both positive values.
Answer:
weight1 = float(input("Enter the weight of first package: "))
price1 = float(input("Enter the price of first package: "))
weight2 = float(input("Enter the weight of second package: "))
price2 = float(input("Enter the price of second package: "))
if weight1 > 0 and price1 > 0 and weight2 > 0 and price2 > 0:
unit_cost1 = price1 / weight1
unit_cost2 = price2 / weight2
if unit_cost1 < unit_cost2:
print("Package 1 has a better price.")
else:
print("Package 2 has a better price.")
else:
print("All the entered values must be positive!")
Explanation:
*The code is in Python.
Ask the user to enter the weight and the price of the packages
Check if the all the values are greater than 0. If they are, calculate the unit price of the packages, divide the prices by weights. Then, compare the unit prices. The package with a smaller unit price has a better price.
If all the entered values are not greater than 0, print a warning message
Type a statement using srand() to seed random number generation using variable seedVal. Then type two statements using rand() to print two random integers between (and including) 0 and 9. End with a newline. Ex: 5 7 Note: For this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). Use two statements for this activity. Also, after calling srand() once, do not call srand() again. (Notes)
GIVEN:
#include
#include // Enables use of rand()
#include // Enables use of time()
int main(void) {
int seedVal = 0;
/* Your solution goes here */
return 0;
}
2). Type two statements that use rand() to print 2 random integers between (and including) 100 and 149. End with a newline. Ex:
101
133
Note: For this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). Use two statements for this activity. Also, srand() has already been called; do not call srand() again.
GIVEN:
#include
#include // Enables use of rand()
#include // Enables use of time()
int main(void) {
int seedVal = 0;
seedVal = 4;
srand(seedVal);
/* Your solution goes here */
return 0;
}
Answer:
1. The solution to question 1 is as follows;
srand(seedVal);
cout<<rand()%10<<endl;
cout<<rand()%10<<endl;
2. The solution to question 2 is as follows
cout<<100+rand()%50 <<endl;
cout<<100+rand()%50 <<endl;
Explanation:
The general syntax to generate random number between interval is
Random Number = Lower Limit + rand() % (Upper Limit - Lower Limit + 1)
In 1;
The solution starts by calling srand(seedVal);
The next two statements is explained as follows
To print two random integers between intervals of 0 and 9 using rand()"
Here, the lower limit = 0
the upper limit = 9
By substituting these values in the formula above; the random number will be generated as thus;
Random Number = 0 + rand() % (9 - 0 + 1)
Random Number = 0 + rand() % (10)
Random Number = rand() % (10)
So, the instruction to generate the two random variables is rand() % (10)
2.
Similar to 1 above
To print two random integers between intervals of 100 and 149 using rand()"
Here, the lower limit = 100
upper limit = 149
By substituting these values in the formula above; the random number will be generated as thus;
Random Number = 100 + rand() % (149 - 100 + 1)
Random Number = 100 + rand() % (50)
So, the instruction to generate the two random variables is 100 + rand() % (50)
Consider that a large online company that provides a widely used search engine, social network, and/or news service is considering banning ads for the following products and services from its site: e-cigarettes, abortion clinics, ice cream, and sugared soft drinks. Which, if any, do you think they should ban? Give reasons. In particular, if you select some but not all, explain the criteria for distinguishing.
Answer:
I think that they should ban ads for all four products. These products, e-cigarettes, abortion clinics, ice cream, and sugared soft drinks, are all discreet adult products that should not be advertised because of their health hazards. Since the "large online company provides a widely used search engine, social network, and/or news service, which are mainly patronized by younger people, such ads that promote products injurious to individual health should be banned. Those who really need or want these products know where they could get them. Therefore, the products should not be made easily accessible to all people. Nor, should ads promote their patronage among the general population.
Explanation:
Advertisements create lasting and powerful images which glamourize some products, thereby causing the general population, especially children, to want to consume them without any discrimination of their health implications. If online banning is then contemplated, there should not be any distinguishing among the four products: e-cigarettes, abortion clinics, ice cream, and sugared soft drinks.
