Recently I was using a pair of 2d arrays. Let me tell you I really regret it. First I just tried making them private class members allocated on the stack, and that really just screwed everything up. It was a pain making sure arrays or elements were getting around ok, and it seemed every single time I tried just using one of them for something menial it would either not compile or do something else completely unexpected.
Eventually I just said screw it, and went dynamic. Sure enough, making a 2d dynamic array is kind of weird, but I thought "Oh well suck it up, too late to get out of this now". Yeah that didn't really help either.
I leave it to your imagination on how I still suffered horrors before I finally got things to work the way I wanted them to. I really wish it was mentioned somewhere in one of my books that MD are one of the most absolutely painful things to work with.
So, what's a not-so-pleasant past experience of yours with C++?
