Is there a reason you are encoding the date as the integer 20,100,103 instead of the number of seconds past the epoch or as a julian date? The reason I ask is that there are oodles of Date, Date/Time, and Julian Date classes out there for you to steal, er, utilize. But if you need the date to be in the aforementioned integer, you will have to manage how you add and subtract dates. Subtracting 1 will not work as intended:
20010102
20010101
20010099
20010098
Nor will adding 1:
20010227
20010228
20010229
20010230

From reading my C book, Im aware that the integers have a maximum value which depends on what type of processor you are using (since they use 16-bit or 32-bit instructions).
Now I know pointers are very flexible, since they can reference anything, but in the case of integer pointers, can they... (4 Replies)
