C Program to Add Two Numbers Without '+' Operator

✅ C Program to Add Two Numbers Without '+' Operator

#include <stdio.h>

int main() {
    int a, b;
    printf("Enter two numbers:\n");
    scanf("%d %d", &a, &b);

    while (b != 0) {
        int carry = a & b;     // Calculate carry
        a = a ^ b;             // Add without carrying
        b = carry << 1;        // Shift carry to the left
    }

    printf("Sum is: %d\n", a);
    return 0;
}
  

📘 Explanation:

This program adds two numbers without using the + operator. It uses bitwise operations:

• a ^ b calculates the sum without carry
• a & b finds the carry
• carry << 1 shifts the carry to the next bit
• The loop continues until there’s no carry

🖥️ Sample Output:

Enter two numbers:
5 3
Sum is: 8
