Hello, I've downloaded MS Visual C++ 2005 beta and want to start coding with it. Most of my experience is with command line unix based compilers (g++, etc), not gui compilers like this, so when I tried to test a real simple program: #include <iostream> int main () { cout << "Hello, World!"; return 0; } I get this error message: error C2065: 'cout' : undeclared identifier I've checked everything I could think of, even the default path for all includes under setting tools->options, which was correct. Maybe I'm missing something simple. Thanks
