 Hi,
I'm writing a code that has to be as efficient as possible both in terms of
memory use and execution speed. I'll have to pass a class instance (which is
an 'intelligent' array) to a function (multiple times). Taking this into
consideration, should I pass it as a pointer or reference? Is there any book
or site that teaches stuff like this (optimizing code for performance)?
thanks for any help
