Hello World in C

Introduction

"Hello World" is a simple program that is used to demonstrate the basic syntax of a programming language. The program's output is a greeting message, typically "Hello, world!". In this tutorial, we will show you how to write the "Hello World" program in C language.

Steps to Follow

Step 1: Open a Text Editor

Open a new text file in a text editor of your choice.
