C Programming Language Tutorial

C language Tutorial with programming approach for beginners and professionals helps you to understand the C language tutorial easily. Our C tutorial explains each topic with programs.
The C Language is developed by Dennis Ritchie for creating system applications that directly interact with the hardware devices such as drivers, kernels, etc.

C programming is considered as the base for other programming languages, that is why it is known as the mother language.
It can be defined in the following ways:

  1. Mother language
  2. C as a system programming language
  3. C as a procedural language
  4. C as a structured programming language
  5. C as a mid-level programming language

1) C as a mother language

C language is considered the mother language of all modern programming languages because most compilers, JVMs, Kernels, etc. are written in C language, and most programming languages follow C syntax.

2) C as a system programming language

A system programming language is used to create system software. C language is a system programming language because it can be used for low-level programming (e.g., driver and kernel).

3) C as a procedural language

A procedure is known as a function, method, routine, subroutine, etc. A procedural language specifies a series of steps for the program to solve the problem.

4) C as a structured programming language

A structured programming language is a subset of the procedural language. Structure means to break a program into parts or blocks so that it may be easy to understand.

5) C as a mid-level programming language

C is considered a middle-level language because it supports features of both low-level and high-level languages.

A Low-level language is specific to one machine, i.e., machine-dependent. It is fast to run but not easy to understand.
A High-Level language is not specific to one machine, i.e., machine-independent. It is easy to understand.

C Program

In this tutorial, all C programs are given with a C compiler so that you can quickly change the C program code. 

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

Output:

Hello World!

A detailed description of the above program is given in the next chapters.
