Re: C++ help: Understanding pointers?

Usually "a pointer to a pointer" is used with 2d arrays. The first pointer points to an array of pointers, which each point to their own arrays.

The first time I encountered a pointer to a pointer, I was writing a function that set the address of a block of memory I allocated to the address that was passed in.

Can get pretty complicated, usually it's easier to draw a picture.
