How to add 2 numbers without using plus symbol in C?

Lets write a C program to perform addition of 2 numbers without using plus symbol or the addition operator (+). In this video tutorial we are using ~ (tilde symbol) bitwise complement operator to perform the operation to get to the anticipated result. Example: If user enters 2 numbers. a = 8 and b = 7.

How do you add two numbers together in C program?

C program to add two numbers Adding a to b (assuming b >= 0) is equivalent to adding one b times to a. For instance, 3 + 5 = 3 + 1 + 1 + 1 + 1 + 1 (adding one five times to 3).

How to add two numbers without using arithmetic operators in C?

Add two numbers without using arithmetic operators. Write a function Add() that returns sum of two integers. The function should not use any of the arithmetic operators (+, ++, –, -, .. etc). Sum of two bits can be obtained by performing XOR (^) of the two bits. Carry bit can be obtained by performing AND (&) of two bits.

What is addition in C with example?
