How to include certain functions without importing the whole namespace

Question

I've been told that it's bad to include the whole std namespace, but I don't know how I can include certain functions like cout, cin, endl.

Answer 1

Shizuku what you mean by "you can't include them without \"using namespace\" syntax"? We include them using #include directive, "using namespace" syntax only let's us use the functions without mentioning the name of the namespace

Answer 2

Shizuku no problem, cheer up (◠‿・)—☆

Thank you, is it there a way to put all of the functions I need from the standard library into one line, or it is the way it is

Answer 6

You can use those symbols (cin, cout …) by simply prefix std:: to their name.
e.g.) std::cout << "Hello" << std::endl

But probably you can't include them with "using namespace" syntax.
