Write a C program to multiply two numbers using plus operator

Given two numbers as input from user, we have to multiply them without using arithmetic operators like * and +. In this program we will multiply two numbers by repetitive addition. In other words, A X B is same as A + A + A… (B times).

For Example : : 

5 X 4 = 5 + 5 + 5 + 5 = 20

Below is the source code for C program to multiply two numbers using plus operator which is successfully compiled and run on Windows System to produce desired output as shown below :

SOURCE CODE : :

/*  C program to multiply two numbers using plus operator  */

#include <stdio.h>

int main()
{
    int a,b;
    int mul,i;

    printf("Enter first number:: ");
    scanf("%d",&a);
    printf("\nEnter second number:: ");
    scanf("%d",&b);

    mul=0;
    for(i=1;i<=b;i++){
        mul += a;
    }
    printf("\nMultiplication of %d and %d is: %d\n",a,b,mul);
     return 0;
}

OUTPUT : :

/*  C program to multiply two numbers using plus operator  */

Enter first number:: 6

Enter second number:: 7

Multiplication of 6 and 7 is: 42
