I am enjoying this series that Casey has done. Takes me back to the old days. I haven't programmed for a while since my business had me doing other things but now I have the time to start again. I am finding however that not much has changed.C++ is as futsy as it ever was. Part of the appeal I guess. It's a pain sometimes because of it's demands but the fact that you can "wrench' on it forever if you want makes it ideal for creating things. I am stuck at Day 15 with an IO file problem. I spent yesterday in VS and in the dos shell trying to resolve it myself. I had it narrowed down to preprocessor issues but stopped there. This morning I searched the forum and found the answer. Thanks rooc. Looks like I wasn't the only one that couldn't compile Day 15. I'm way behind everyone with no hopes of catching up but still having fun doing the code from the beginning.
