It depends upon what you are trying to do here. If your intent is to write and run C++ programs on your desktop/laptop, CodeWarrior does not do that. (It used to be able to generate Windows apps, but that capability has been discontinued years ago.)
If you are going to be writing programs for embedded processors, you need to tell us which processor you are targeting before we can give you an answer. As you have noticed, there are many different versions of CodeWarrior, each which generates code for a specific processor.
