Re: Feedback on C code?
You'll probably want to pass the board as a pointer along with the width and height, then do int value = board[x*height+width]. You can't pass arrays by value; if you want to do that, you'd do something like:
struct Board {
int *data;
size_t width, height;
};
int readBoard(struct Board *board, size_t x, size_t y) {
return board->data[board->height*x+y];
}then use memory allocation functions to allocate board. ALternatively, put the array in the struct, which stops a thing called pointer decay from happening.
You want the width as well because that will let you check whether x is right--in practice you'd have a debug-only bounds check here with assert or something.
I had to look up the semantics, but basically arrays are converted to pointers when passed to functions, and int board[] is just a fancy way of saying pointer to int. I had to look it up because it's not done in practice, since (in C at any rate) you can't make a function that works on any size of array.
C and C++ are different as well. (most) C compiles as C++. Very little C++ compiles as C. C++ is something like literally 10 to 20 times as complicated as C. I'd not try to get C++ resources teaching you C for that reason, though in this case you'd have the same problem in C++ as far as I know. C++ people have a set of solutions to this that are sort of better, but explaining non-type template parameters is very much not worth it until after you've had 5 or 6 other explanations of C++ things.
