Hello!

I wonder how I can check that a input made by a user, really is an integer and not anything else.

int main(void)
{
   int test;
   cout << "Enter integer: ";
   cin >> test;

   // Now I want to check that the user really entered an
   // integer and not anything else.

Add this:

Code: [Select]


   if(cin.fail())
   {
       // a number wasn't entered
   }
   else
   {
      if(!cin.eof())
      {
          // there is more non-numeric input
      }
   }
}
