Addition of two Numbers in C

The Addition of two numbers in c with the help of arithmetic operator and print the sum of two numbers. for example we enter two number is 6,6 and the sum is equal to 12.

#include<stdio.h>

#include<conio.h>

  void main()

  {

   int a,b,sum;

    printf("enter two numbers\n");

       sum=a+b;

         printf("sum of two numbers=%d",sum);

          getch();

      }

similarly, we create subtraction,multiplication,division program.

Addition using without third variable 

#include<stdio.h>

#include<conio.h>

  void main()

{

int a,b;

 printf("enter the two numbers\n");

  scanf("%d%d",&a,&b);

   a=a+b;

    printf("sum of two numbers=%d",a);

     getch();

}

Don't Recommended this Because of the the original value of a is lost so we cannot use any where the  original value of 'a'.

Output:-
