Answer 1

Answer:

#include<iostream>

int Add(int, int);

int main()  

{  

   int r,a;

   std::cin>>r>>a;

   std::cout<< Add(r,a);  

   return 0;  

}  

int Add(int x, int y)  

{  

   int carry;

   while (y != 0)  

   {  

      int carry = x & y;

      x= x ^ y;

      y = carry << 1;

   }  

   return x;  

}
