hi friends i m new to this group, i found very interesting and useful
discussion here....
this is code for adding two number without arithmetic operator
int add(int a, int b)
{
do
{
a=a^b;
b=(a^b)&b;
b=b<<1;
} while(b);
return(a);
}
it is working well for negative numbers also . i tried lot but can not
understand logic behind it can any one explain it in easy manner ...
thanks in advance
