I need help with pointers

asdasd12345 · 2003-10-07T20:53:12

So far Ive been reading my C++ book and looking up tutorials online and I really dont understand the point of pointers. I mean what kind of situations would you really want to use them in. As far as I understand them pointers are variables that hold the address of another variable..or something like that. Any help would be helpful, apart from help that isnt helpful.

Hey Rick, that was pretty helpful, I didn''t understand pointers before reading that. The others ones that go into open gl, besides the one about linked lists, were not helpful at all.

Pointers are good in a GUI also. Suppose you write a TextBox class and have an instance of it where you enter what you want the Player''s name to be. In the Player class, he has a name variable which is a pointer to whatever variable is held by the textbox. So change it in the box, you change it in the player class as well. Simplified example, but ya get the point.
