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

returning function to menu option 1 and menu option 2. This means that you will create two functions: an add function and a multiply function. The functions will receive two doubles and return a double. The following is code I have written to complete this assignment. When entering option 3 after entering option 1 or 2, it does not exit from the program. Also, the menu is appended instead of deleting everything and displaying the original menu.#include #include #include 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(){ 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" "\nEnter an option: "; cin >> option; switch (option) { case 1:option1; int option1 ();{ double num1 = 0; double num2 = 0;// void int key = 0; cout << "\n Enter a number: "; cin >> num1; cout<< "\n Enter a second number: "; cin >> num2; double sum = addition(num1, num2); cout << "\n Sum is: " << sum <> key; system("cls");} break; case 2: option2; int option2 ();{ double num1 = 0; double num2 = 0;cout << "\n Enter a number:";cin >> num1;cout << "\n Enter a second number: ";cin >> num2;double product = multiplication(num1, num2); cout << "\n Product is: " << product << endl;system("cls");} break; case 3: option3; int option3(); {return 0;} break; default: cout << "\n Invalid number entered: ";}////do {main();}//while (option < 3);}double addition(double num1, double num2){ return num1 + num2;}double multiplication(double num1, double num2){ return num1*num2;}

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!

Explanation:

In excel "autofill" is used to fill data in cells, which follows the pattern or logic applied in other cells. To apply same calculation of A20 in B20 to H20, we use autofill technique. Instead of copy pasting, or manually entering the complex formula this method is more suitable.
