What is C Language? Write a program in c Language.

Introduction: 

What is C Language?

In computing C is a general purpose programming language developed by Dennis Ritchie at “AT & T’s Bell Laboratories” of USA in 1972.

This language was created for a specific purpose i.e. to design the UNIX operating system. The UNIX operating system and virtually all UNIX applications are written in the C language. C has now become a widely used professional language for various reasons which are:

·         Easy to learn

·         Structured language

·         It produces efficient programs.

·         It can handle low-level activities.

·         It can be compiled on a variety of computers.

Some Facts about C Language

·         C was basically invented to write an operating system called UNIX.

·         C language is a successor of B language which was introduced around 1970

·         The language was formalized in 1988 by the American National Standard Institute (ANSI).

·         C is a procedural language.

·         Today C is the most widely used System Programming Language.

·         C language influenced most of the modern world programming languages which include the mighty C++ and Java as well.

Now let’s create a program to calculate sum of two numbers using C language

#include<stdio.h>
#include<conio.h>
void main()
{
  int a,b,sum;
  clrsrc();
  printf("Enter value of a=");
  scanf("%d",&a);
  printf(" Enter value of b=");
  scanf("%d",&b);
  sum=a+b;
  printf("Sum of %d and %d = %d"a,b,sum);
  getch();
}

Run the program using ctrl+F9

Output will be:
Enter value of a= 50
Enter value of b= 30
Sum of 50 and 30 = 80

Difference b
