Create the Following Menu in a loop so the menu will continually show until the user chooses to exit.AddMultiplyExitAdd a value

ycow [4]

Answer:

I have added the code again with the mistakes are corrected please see the comments in code. You have mistake in while loop condition.

#include <iostream>

#include <iomanip>

#include <cmath>

using namespace std;

int options ();

int option1 ();

int option2 ();

int option3 ();

double addition (double num1, double num2);

double multiplication (double num1, double num2);

int main()

{

jump:

int option = 0;

cout << "1. Add" << endl;

cout << "2. Multiply" << endl;

cout << "3. Exit" << endl;

cout << "Enter option 1 for addition, option 2 for multiplication, or option 3 to exit" "Enter an option: ";

cin >> option;

switch (option)

{

case 1:option1;

int option1 ();

{

double num1 = 0;

double num2 = 0;

// void int key = 0;

cout << " Enter a number: ";

cin >> num1;

cout<< " Enter a second number: ";

cin >> num2;

double sum = addition(num1, num2);

cout << " Sum is: " << sum <<endl;

} break;

case 2: option2;

int option2 ();

{

double num1 = 0;

double num2 = 0;

cout << " Enter a number:";

cin >> num1;

cout << " Enter a second number: ";

cin >> num2;

double product = multiplication(num1, num2);

cout << " Product is: " << product << endl;

//system("cls");

}

break;

case 3: option3;

int option3();

{

return 0;

}

break;

default: cout << " Invalid number entered: ";

}

//do {main();}

//while (option < 3); //you have mistake in this loop please have a look

while (option<3)

{

goto jump;

}

double addition(double num1, double num2)

{

return num1 + num2;

}

double multiplication(double num1, double num2)

{

return num1*num2;

}

Explanation:

You can also do this by using goto statement in switch case and menu will be repeated until the user not select to exit and now it will work with the loop as well.

I hope it will help you!

Suppose 8 people want to communicate with each other using public key encryption. The communication between any pair of them is

ludmilkaskok [199]

Answer:

The answer is "64"

Explanation:

There has been 1 Private Key 1 Public Key for every person. The private key is used for other app messages. All else uses the Public Key to encrypt messages with that user. Those keys are numerically related. Even if you have 5 users, you will be given 5 Personal keys and 5 Public keys.

All user will have a duplicate of other public keys, which indicates (n*n-1) copies of n public keys on different systems to make sure shared contact between all users, plus n private keys.

The unique key count is 2n, with n^2 distributed private and public keys on different systems.
8 people, where 8 is a number, that is equal to n so, $n^2 = 8^2 =8 \times 8 = 64$
