I've a cousing who is very much interested in programming. He started with C++ and now moved into Python.

But there are some problems. Here is an example: He knows he can use pointers to get the memory address location of a variable. But when it returns something like 0x0123, he doesn't know about hexadecimal numbers!

He's currently in his 6th form, but his interest in programming is far beyond the kids his age. I would like to get suggestions to lead him in the right way. Any ideas?
