Add Two Integers Without Using Arithmetic Operators

❮ Previous Next ❯

A Python program to add two integers without using the + operator, using bitwise operations.

Explanation of the Python Program in Points:

Function Definition:
- add_two_numbers(a, b) function is created to add two numbers without using the + operator.
Bitwise Addition:
- Uses bitwise operations (AND, XOR, and Left Shift) to perform addition.
Loop Until Carry is Zero:
- A while loop runs until b (carry) becomes 0.
Calculate Carry:
- carry = a & b → Identifies common set bits where a carry would occur.
Sum Without Carry:
- a = a ^ b → Adds numbers without considering the carry.
Shift Carry Left:
- b = carry << 1 → Moves the carry one position left for the next bit addition.
Repeat Until No Carry Left:
- The loop continues until b becomes 0, and a holds the final sum.
User Input and Output:
- Takes two numbers as input from the user and prints their sum.

Program:

def add_to_numbers(a, b):

    while b != 0:

        carry = a & b  

        a = a ^ b      

        b = carry << 1

    return a


num1 = int(input("Enter first number: "))

num2 = int(input("Enter second number: "))

print("Sum:", add_to_numbers(num1, num2))
