How to include certain functions without importing the whole namespace

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.

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

Rishi Oh my mistake, without --> with I thought he is confused with using namespace and include, what Martin Taylor says is correct. Fixed for no more confusion to not arise... sorry šŸ˜“

Martin Taylor 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

You can use those symbols (cin, cout ā€¦) 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.
