Hello All,

What is the use of # in C program?
Eg: #include<stdio.h>
#include<conio.h>

Sorry if posted in wrong place.

Thank you in advance,

Those are known as "preprocessor directives". They give commands to the compiler, as opposed to being actual C statements.

In linux, # represents a program and the compiler checks only the line that is included with # in the configuration files.
