Familiarization with C programming environment

C Programming

In 1972, Dennis M. Ritchie developed C programming, general-purpose, high-level, procedural and imperative computer language, at the Bell Telephone Laboratories. 1972, Dennis M.

Father of C Language

About C language

• C Language is the successor of B language.
• UNIX operating system was built with the help of C programming language.
• It is system software.
• In 1988, the American National Standard Institute(ANSI) standardized the C Language.
• Procedural language.
• Easy to Learn.
• It can handle low-level activities.

First C Program

In the first basic c program, the working of Functions ‘printf()’ and ‘scanf()’ explained

Source Code: –

#include<stdio.h>

int main()

    {    int a,b,c;

         printf("Enter The First Value : ");

         scanf("%d",&a);

         printf("Enter The Second Value : ");

         scanf("%d",&b);

         printf("A = %d\n",a);

         printf("B = %d\n",b);

         c=a+b;

         printf("Addition (A+B) = %d\n",c);

         c=a-b;

         printf("Subtraction (A-B) = %d\n",c);

         c=a*b;

        printf("Multiplication (A*B) = %d\n",c);

        c=a/b;

        printf("Division (A/B) = %d\n",c);

        c=a%b;

        printf("Modulus (A%%B) = %d\n",c);

        return 0;

   }
