No, but if you dont, every single object that is inside the std namespace need to have std:: before it. Example: #include <iostream> using namespace std; ... cout<<1; // Fine ... ---------------- #include <iostream> ... std::cout<<1; // Fine, but needs to have std:: at the beginning If you have a lot of cout statements, using the std namespace is good.
