Returning to main menu

On my calculator, it asks the user what they want to do.(switch/case functions)
After the person adds, subtracts, multiplys or divides the 2 numbers, the calculator exits. Instead of using return 0 and having it exit, how can I have it return to the main menu?

You can use a while loop, and then the last menu item can be something like "Exit". If the person types in the menu number corresponding to exit, then make the while loop terminate.

Thank you. I will see what I can do.

I did something very similar a very long time ago..... (hence not using the standard and all that stuff) help this helps a bit. You may need to add an extra case statement for an exit option or something.

Code:

#include <iostream.h>
#include <conio.h>

void MenuHeader(char Buffer[],int BufferLength);

int main()
{
  const int MAX_BUFFER=512;

  char Buffer[MAX_BUFFER];
  short Answer,Num1,Num2,Quotient,Remainder;
  int MenuNum;

  do
  {
    MenuHeader(Buffer,MAX_BUFFER);
    MenuNum = atoi(Buffer);

    switch(MenuNum)
    {
      case 1: GetNumbers(Num1,Num2,MenuNum);
              Addition(Num1,Num2,Answer);
              DisplayResults(Num1,Num2,Answer,0,0);
              break;
      case 2: GetNumbers(Num1,Num2,MenuNum);
              Subtraction(Num1,Num2,Answer);
              DisplayResults(Num1,Num2,Answer,0,0);
              break;
      case 3: GetNumbers(Num1,Num2,MenuNum);
              Multiply(Num1,Num2,Answer);
              DisplayResults(Num1,Num2,Answer,0,0);
              break;
      case 4: GetNumbers(Num1,Num2,MenuNum);
              Division(Num1,Num2,Quotient,Remainder);
              DisplayResults(Num1,Num2,Quotient,Remainder,MenuNum);
              break;
      case 5: GetNumbers(Num1,Num2,MenuNum);
              Powers(Num1,Num2);
              break;
      case 6: GetNumbers(Num1,Num2,MenuNum);
              EvenNumbers(Num1);
              break;
      case 7: GetNumbers(Num1,Num2,MenuNum);
              ShiftLeft(Num1,Answer);
              DisplayResults(Num1,Num2,Answer,0,0);
              break;
      case 8: GetNumbers(Num1,Num2,MenuNum);
              DecBinary(Num1);
              break;
      case 9: GetNumbers(Num1,Num2,MenuNum);
              Cubes(Num1);
    }
  }while(MenuNum != 10);

  return 0;
}

void MenuHeader(char Buffer[],int BufferLength)
{
  clrscr();
  cout << "******************************Assembler Calculator******************"
      <<"************\n1. Addition\n2. Subtraction\n3. Multiply\n4. Divide\n"

  cin.ignore();
