#include <iostream>
using namespace std;
int main()
{
char x ='a';
char y ='c';
cout << ++x << endl;
cout << y++ << endl;
cout << (x > y) << endl;
cout << (x-y) << endl;
system ("pause");
return 0;
}

Yeah 0 errors, warnings, and 0 of this funky i thing in a white circle

Edit: I posted the iostream part, but for some reason it's not showing on this site????????
