	operator+ overloading problem - GameDev.Net Discussion Forums
		Posted - 7/21/2004 8:58:04 AM operator+ has to create a copy somewhere, otherwise it would be no different to operator+=, creating a copy in the parameter seems like as good a place as any to create it.

		The code is pretty hard to follow, it looks like you are trying to implement a sizeable array of some kind, std::vector already exists for this purpose, would be better off using that, and you could forget about the memory worries you are having.

		Its purpose is to provide new operations on a class or set of related classes without actually altering the classes involved.
		The built-in C operator + produces different types depending on both the type of its left and right argument; both a double plus a float and a float plus a double produce doubles.
		You can certainly stick to virtual methods for each operation, and use partial classes to add each one, but this is just poor design, because it doesn't separate the object from application-specific operations on that object effectively.

	operator+-.. question - GameDev.Net Discussion Forums (Site not responding. Last check: 2007-10-01)*
		A programmer does not usually expect a binary operator to actually alter either one of the arguments; only to return the result.
		Posted - 10/7/2004 1:30:00 PM one good way to overload the general arithmetic operators is to compose them out of the arithmetic assigmenet operators e.g.
		Also, I recommend you change your operator to be a nonmember function to allow for left-hand conversions prior to addition.

		On the other hand, if instead of an array you pass in an object whose only valid non-read-only operation is to exchange two elements, then this becomes statically obvious.
		In short, wherever you find yourself wanting to keep track of a static property as it flows through a program, types are a great way of doing so - use them to catch errors sooner.
