Program for doing sum of 2 numbers without using '+' operator ?

Answer 1

Or we can do :-
int a,b,sum;
sum = - (-a -b);
Just a joke 😂😂😂

Answer 2

#include<stdio.h>
int add(int x, int y) {
int a, b;
do {
a = x & y;
b = x ^ y;
x = a << 1;
y = b; }
while (a);
return b; }
int main( void ){
printf( "2 + 3 = %d", add(2,3));
return 0; }

XOR (x ^ y) is addition without carry. (x & y) is the carry-out from each bit. (x & y) << 1 is the carry-in to each bit.

The loop keeps adding the carries until the carry is zero for all bits.

Answer 3

python:

class oke:
def summing(x, y):
return x.__radd__(y)

print(oke.summing(10, 5))
