I was at a client a couple of years ago, and was introduced to one of their junior programmers, who was busy getting up to speed on their programming languages, techniques, systems etc. One of the senior guys asked her her how she was getting on, and she said all was good, she was ahead of schedule.
So that senior guy said to one of his senior colleagues "Hmmm, maybe it's time to introduce her to pointers, that'll take the smile off her face...."
I can't really see how you can be even a junior programmer without a knowledge of pointers. One
of my personal favourite pointer-based macros.
