C | Introduction

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 keeps fluctuating at number one scale of popularity along with Java programming language, which is also equally popular and most widely used among modern software programmers.

Why to Learn C Programming?

C programming language is a MUST for students and working professionals to become a great Software Engineer specially when they are working in Software Development Domain. I will list down some of the key advantages of learning C Programming:

Easy to learn

Structured language

It produces efficient programs

It can handle low-level activities

It can be compiled on a variety of computer platforms

Hello World using C Programming.

Just to give you a little excitement about C programming, I'm going to give you a small conventional C Programming Hello World program, You can try it using Demo link.

Example

#include

int main() {
/* my first program in C */
printf("Hello, World! \n");

return 0;
}

output

Hello World

Applications of C Programming

C was initially used for system development work, particularly the programs that make-up the operating system. C was adopted as a system development language because it produces code that runs nearly as fast as the code written in assembly language. Some examples of the use of C are -

Operating Systems

Language Compilers

Assemblers

Text Editors

Print Spoolers

Network Drivers

Modern Programs

Databases

Language Interpreters

Utilities

Audience

C is the building block for many other programming languages.
Programs written in C are highly portable.
Several standard functions are there (like in-built) that can be used to develop programs.
C programs are collections of C library functions, and it's also easy to add functions to the C library.
The modular structure makes code debugging, maintenance, and testing easier.

Disadvantages

C does not provide Object Oriented Programming (OOP) concepts.
There are no concepts of Namespace in C.
C does not provide binding or wrapping up of data in a single unit.
C does not provide Constructor and Destructor.
