It is up to you if you want to include the standard namespace library or not.

You might see some C++ programs that run without the standard namespace library.

Omitting Namespace

You might see some C++ programs that run without the standard namespace library. The using namespace std line can be omitted and replaced with the std keyword, followed by the :: operator for string (and cout ) objects:

Example

#include <iostream>
#include <string>
// using namespace std; - Remove this line int main() { std:: string greeting = "Hello"; std:: cout << greeting;
return 0;
}

It is up to you if you want to include the standard namespace library or not.

In our tutorial, we will continue to include the library.
