Say I have this class: class RandomClass { struct RandomStruct rs; ... }; If I do not instantiate rs with the new operator it lies on the stack right? So What if I decide that I want to instantiate RandomClass with the new operator. Even though I didnt use new on rs will it be on the Heap with my class? Also, I am kinda confused as to why I need new at all. Cant I just do something like this: //global struct RandomStruct rs; int WINAPI WinMain(...) { rs(...) } and use rs throughout my entire program. And One more question: What is the rule of thumb as to when to use the new operator? I see that most people don't "new" bools and ints in Classes, yet some other class members are "newed".

Members use the memory location of their container class. See the first part of this article, for instance.

You don't need "new" : you can use the standard library containers to allocate and manage your objects for you. People use "new" when they want to manage the lifetime of their object themselves.
