Use of a # in C programming language?

[SandraJose]

Hi

What is the actual intent of # in C programming language? For an instance: #include<#include stdio.h> & #include <conio.h>

Actually, # is the preprocessor directives, as it provides an simpler way of compilation of a programming, modify and many more useful features. In Linux # represents a program and the compiler to checks only the line that is added with # in the configuration files.
