visual studio .net 03

hi yaz! :wave:

i'm taking my first programing course this semester and already have some problems - that stupid microsoft program thingy doesn't wanna run my program!!!! :mad:

here is my code:

#include <iostream>
using namespace std;

int main()
cout<<"Testing 1, 2, 3\n";
return 0;

when i click compile i get the following error:
"fatal error C1010: unexpected end of file while looking for precompiled header directive"

i copied the program right out of the book so it can't be wrong. wut gives??? :confused:
