Umesh sharma  (9 years ago)

say you have the following code
for(int i=0;i0;i--){}

But if you do not even want to use increment or decrement operators then you can do it in the following way (its a C program):

#include
#include

int Add(int x, int y)
{
if (y == 0)
return x;
else
return Add( x ^ y, (x & y)
