There is a fix, buts thats just a small hack I came up with...

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

int main()
{
  int i=INT_MIN;
  cout << "Enter your digit: ";
  cout.flush();
  cin >> i;
  if(i > INT_MIN)
    cout << "Thanks for the integer." << endl;
  else
    cout << "WTF. No integer?" << endl;
  return i;
}

But, then again, if the user inputs a value repressenting INT_MIN (which on 32bit architecture is -2147483648 ) it will fail.. Yet, who would want to use that as the input value?
