In C++, the built in C++ library routines are kept in the standard namespace. That includes stuff like cout, cin, string, vector, map, etc and so they left it as using namespace std; which is shorter than typing all that^^^^.

without using namespace std; you would have to put std:: before a lot of stuff e.g: std::cout << "this is exhausting"
