Introduction to C Programming Language


C programming is a general-purpose, procedural, imperative computer programming language developed in 1972 by Dennis M. Ritchie at the Bell Telephone Laboratories to develop the UNIX operating system. C is the most widely used computer language.

It can be used to develop software like operating systems, databases, compilers, and so on. C programming is an excellent language to learn to program for beginners.

Why Learn C Programming?

C programming language is a MUST for students and working professionals to become great Software Engineers especially when they are working in Software Development Domain. Some of the key advantages of learning C Programming:

  • C helps you to understand the internal architecture of a computer, how the computer stores and retrieves information.
  • After learning C, it will be much easier to learn other programming languages like Java, Python, etc.
  • Opportunity to work on open source projects. Some of the largest open-source projects such as Linux kernel, Python interpreter, SQLite database, etc. are written in C programming.

Facts about C

  • C was invented to write an operating system called UNIX.
  • C is a successor of B language which was introduced around the early 1970s.
  • The language was formalized in 1988 by the American National Standard Institute (ANSI).
  • The UNIX OS was totally written in C.
  • Today C is the most widely used and popular System Programming Language.
  • Most of the state-of-the-art software have been implemented using C.

About C Programming

  • Procedural Language – Instructions in a C program are executed step by step.
  • Portable – You can move C programs from one platform to another, and run it without any or minimal changes.
  • Speed – C programming is faster than most programming languages like Java, Python, etc.
  • General Purpose – C programming can be used to develop operating systems, embedded systems, databases, and so on.

Hello World using C Programming

#include <stdio.h> int main() { /* my first program in C */ printf("Hello, World! \n"); return 0;
