How can one use a function from the standard library of C++ ?

by including the correct library with #include <{libraryName}>

by using std::{function} to call the wanted function

by including using namespace std at at beginning of the file

by including the correct library and using std::{function}

???

Some functions and classes of the standard library are not included by default, such as vector. In this case writing std::vector(...) doesn't suffice to use the class. One needs to add #include <vector> as well.
