    C++ Iomanip

    I'm just wondering what exactly does #include <iomanip> do? I've been looking it but I'm not really understanding what exactly it does to a code. If anyone can explain to me thanks.

    By it's self it does nothing to your code. It allows you to use the functions it prototypes in your program, for example the setw() manipulator is prototyped in this header.

    It includes a header that allows you to use some functionality in the standard library that has to do with I/O stream manipulation.
