Write a C Program to Add Two Numbers Without Plus(+) Operator

Add Two Numbers Without Plus(+) Operator

Logic

1. Take two numbers from user.

2. c = a - ~b -1;

~ it represents 1's complement.  So the above equation becomes

a-(-b + 1) + 1

a + b – 1 + 1

a + b 

#include <stdio.h>

void main()

{

  int a,b,c;

  printf("Enter two numbers");

  scanf("%d%d",&a,&b);

  c = a - ~b - 1;

  printf("Addition of two numbers is",c);

}
