In Visual C++ all I've done is use the
Code:
system("pause")

and
Code:
cin.get()

to stop the program from closing itself immediately, but I was wondering if there was a way to restart the program instead of closing it? Or a code that stops the program from closing until you click the X on the top right hand corner.

_getch()

but if you ran the program from the command line you wouldn't have this issue in the first place

you can also use the goto syntax and the systen("cls") and system("pause>nul")

code template:

Code:

#include <iostream>
#include <stdlib.h>
using namespace std;

int main()
{
begin:
cout << "Hello World!\n";
system("pause>nul"); //wait till keyboard pressed
system("cls"); //erase all from command line
goto begin;
return 0;
}


never ending*

use with switch function for better resault.

ugh, goto is nasty
behold my probably less than perfect example.

Code:
#include <iostream>
using namespace std;

char option;

int main ()
{

   while (option != 'n')
   {
      cout << "1. Diques\n";
      cout << "2. Coques\n\n";
      cin >> option; 

      switch(option)
      {
      case '1':
         cout << "Diques\n";
         cout << "Want to do something else? (y / n) ";
         cin >> option;
         break;

      case '2':      
         cout << "Coques\n";
         cout << "Want to do something else? (y / n) ";
         cin >> option;
         break;

      case 'y':      
         cout << "1. Diques\n";
         cout << "2. Coques\n\n";
         cin >> option; 
         break;
      }
   }
   return 0;
}

You should use a do-while loop instead of a while loop because you do not yet have any input at the beginning of the program.
