C is a general-purpose, procedural, imperative programming language.  It can be used to develop software like operating systems, databases, compilers. C programming is considered as the base for other programming languages.

C Language is developed by Dennis Ritchie in 1972, at the Bell Telephone Laboratories to develop the UNIX operating system. It can be used to develop system applications that directly interact with hardware devices.

Facts about C

  • It is a System programming language
  • It is a procedural programming language. (ie- Instructions in a C program are executed step by step)
  • It is a Structured programming language.
  • C is a successor of B language which was introduced around the 1970s.
  • The UNIX OS was totally written in C.
  • C programming is faster than most programming languages like Java, Python, etc.

C Program

#include <stdio.h>
int main() {
   printf("Hello, World! \n");
   return 0;

Real-World Applications of C Programming

C was a system development language because it produces code that runs nearly as fast as the code written in assembly language. C is regarded as one of the oldest and fundamental languages widely used all over the world. Some real world applications of C are following.

  • Operating Systems
  • Embedded Systems
  • Language Compilers
  • GUI (Graphical User Interface)
  • Text Editors
  • New Programming Language
  • Gaming and Animation
  • Network Drivers
  • Databases
  • IDEs (Integrated Development Environments)
