Use minus operator :-
int a=10,b=20,c;
c=a-(-b);

#include add(int a,int b)
{
 if(!a) return b;
else return add((a&b)<<1,a^b);
}
void main()
{ int a=2, b=5,c; c= add(a,b);
cout<<c;
}


hope it 'll help you right...........

For two positive numbers:

int main(){
int a = 10;
int b = 10;

printf("%d",a ^ b | ((a & b)<< 1));
return 0;
}
