Best ResponseYou've already chosen the best response.0If they hold different (integral) values, use the following swap. template<typename T> inline void swap(T &l, T &r) { l ^= r; r ^= l; l ^= r; } Why don't you just use std::swap?

Best ResponseYou've already chosen the best response.0You need to be very careful using the methods above. You may introduce a bug that causes some values to work and others to fail (this is due to overflow). I believe xor is safer than addition in this case.

Best ResponseYou've already chosen the best response.0The XOR will not cause overflow.
