I've noticed something odd in most of the books/tutorials I've read that deal with 2D arrays, including the current book I'm reading, Tom Swan's C++ Primer (1992).
From what I've read, in C++, the standard way to order the indicies is row#, column#.
The problem I have with that is that I think of coordinates in terms of (X, Y). Picking the ROW number first is effectively the same as picking the Y-coordinate; picking the column number is the same as picking the X-coordinate. This means that the coordinates are (Y, X), not (X, Y).
I find this confusing, and so I use (X, Y). The question is: Does this matter? If I order my array (x, y) instead of (y, x), will others be confused by my code? Which way should I use?
