Answer Posted / niranjan vg
#include<stdio.h>
int main()
{
int a,b,sum,carry;
printf("\n Enter the numbers : ");
scanf("%d%d",&a,&b);
sum=a^b;
carry=a&b; // Produce a extra carry bit if present
while(carry!=0)
{
carry<<=1; // shift for every iteration so
that it gets added with the next digit
a=sum;
b=carry;
sum=a^b; // perform Xor Operation
carry=a&b; // Calculate the new value for carry
}
printf("\n The sum is %d", sum);
}
