Add without Addition Operator

This is a simple  Program in C to print sum or addition of two numbers without using Arithmetical operators. This is a part of Mumbai University MCA Colleges. It is mostly asked in Interviews.

Add without Arithmetic Operators

#include <stdio.h>

#include <iostream.h>

int main()

{

int a=7,b=5;

while(b--) // b will take value 5,4,3,2,1,0

a++;    // a will take values 7,8,9,10,11,12

cout<<a;

}

Here what we have done is that we have run a added the number 1 or incremented the value of variable by 1 and decremented the other by 1 till the decremented variable is 0.

The number of times the loop runs for 'b', that many times the value of a will increase.

Hope this Program is useful to you in some sense or other. Keep on following this blog for more Mumbai University MCA College Programs. Happy Programming and Studying.
