Question

What does #include mean in c++ programs ???

Answer 1

Explanation:

Honestly, I've searched through online, but didn't got any, and only spotted # on the end of CC+ explanation thing or something...

Commonly used header files:

<iostream> //input/output

<cmath> //math functions

<string> //string functions

<iomanip> //formatting manipulations for input/output

Using string Data Type:

Must access definition from header file string

Include following preprocessor directive:

#include<string>

But what I know about # in programming tho in my own experience nonetheless, it has something to do with numbers? Especially in headings tho XD
