C is a general-purpose procedural programming language initially developed by Dennis Ritchie in 1972 at Bell Laboratories of AT&T Labs. It was mainly created as a system programming language to write the UNIX operating system.

Why Learn C?

• C is considered mother of all programming languages as many later languages like Java, PHP and JavaScript have borrowed syntax/features directly or indirectly from the C.
• If a person learns C programming first, it helps to learn any modern programming language as it provide a deeper understanding of the fundamentals of programming and underlying architecture of the operating system like pointers, working with memory locations etc.
• C is widely used in operating systems, embedded systems, compilers, databases, networking, game engines, and real-time systems for its efficiency to work in low resource environment and hardware-level support.

Writing First Program in C Language

This simple program demonstrates the basic structure of a C program. It will also help us understand the basic syntax of a C program.

#include <stdio.h>

int main(void)

{

    // This prints "Hello World"

    printf("Hello World");

    return 0;  

}
