What does this program?

[Thebeatboxer]

Hi! I saw a picture with a program and i am wondering what it does. I tested and it freezes the .exe. Can you tell me why?

#include <iostream>
using namespace std;
int main;
{for(; ; )
cout<<'\a';
return 0;
}

Aside from the typos making this an invalid program, it creates an infinite loop that outputs the '\a' character infinitely.

Recall that in a for loop, all three parts are optional.
