Variables and Pointers
I've been a professional programmer for a while now. I blazed through a couple of high-level C courses, never intending to program in C, and proceeded to become relatively expert level in perl. After that I became intermediate-to-senior in Java, and quite comfortable with PHP.The result of all that though is that I never got very schooled in low-level programming. Well, I did actually take an assembly language course once and actually find it quite fun. But I never really paid much attention to C. None of my other languages have ever forced me to actually pay attention to memory locations.
Which means that I've never had much reason to pay attention to pointers. I know the concepts of passing by reference versus passing by value, but pointers are something different.
I'm learning some Objective-C right now, so I'm having to review this. I know I've learned all this before so it should be quick review.
Notes upcoming in another entry. You can just ignore the next entry entirely if you want. I'll come back to writing English soon.
