Why std::cout instead of simply cout?

Question

I get these error messages for all cout and endl:

main.cc:17:5: error: ‘cout’ was not declared in this scope
main.cc:17:5: note: sugges         


        

Answer 1

Everything in the Standard Template/Iostream Library resides in namespace std. You've probably used:

using namespace std;

In your classes, and that's why it worked.
