Before starting to learn the C language, you need to learn how to write, compile and run the first c program i.e. hello world,

To write the first c program, open the C console and write the following code:

hello world

Following are the meaning of the written code:

#include :means includes the standard input output library functions. Because The printf() function is defined in stdio.h .
