could just put the whole program of main() in a do while loop, then at the end of the function have the user input 'y' or 'n' for whether they want to run again.

can you give me example of do while loop?

#include <iostream>

int main()
{
   do{
   //code code
  }while(/*condition*/)
  //before the system pause (where your if loop currently is)

}


I however prefer to just use a while loop... basically you just don't do the do part, and state the condition in the beginning (which prevents confusion)

for more info on loops read: http://cplusplus.com/doc/tutorial/control/

Cheers!

You don't put a condition after do !!!
