Also, noticed your code is flawed, you never used a namespace, nor explicitly
stated one. cout is part of the 'std' namespace, so either ' using namespace
std;' for global/local use of namespace, OR do 'std::cout <<' instead. Try the
hello.cpp I sent you in the last email, that one should work for ya :)
