Add two numbers in c without using operator

#include<stdio.h>

int main(){
   
    int a,b;
    int sum;

    printf("Enter any two integers: ");
    scanf("%d%d",&a,&b);

    //sum = a - (-b);
    sum = a - ~b -1;

    printf("Sum of two integers: %d",sum);

    return 0;
}
Sample output: Enter any two integers: 5 10 Sum of two integers: 15 Algorithm:
In c ~ is 1's complement operator. This is equivalent to: ~a = -b + 1 So, a - ~b -1 = a-(-b + 1) + 1 = a + b – 1 + 1 = a + b
