Whether it is C, C++, ASM, or C#, its going to be a lot faster to work
with pointers than to copy around data for every little thing you do.
(This is, of course, if the size is greater than the size of the actual
pointer).
Let's use this class as an example:
class MyClass {
private:
unsigned long long mem0;
.....
unsigned long long mem31;
};
It would be much quicker to push and pop a 4-byte pointer than to push
and pop a 256-byte class for everything you do with it. Hence, C++ gives
us the "->" operator for object pointers.
