Code:

#include <iostream.h>

int main()
{
   int digit;
   
   cout << "Enter a number: ";
   cin >> digit;
   
   if(cin.fail())
   {
      cin.clear(1);
      cin.ignore(80, '\n');
      
      cout << "Hey you idiot! I said number." << endl;
   }
   
   return 0;
}

Or something similar

I agree with Ronin.
Use If then or Switch statements. They are easy and hassle-free.
