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

If you want to extract the parts of the date, then:
The reason for me using that style of date is because that is what exists in my database. For the time being I wrote some code which I will post below. I wouldn't mind converting to a Julian style date or some other style if that will help me deal with things I just have not got there yet. Thanks for your reply:
You need to account for leap-years:
Please keep in mind that this will only work properly if your dates occurs between the years 1901 and 2099. A more accurate implemention would be:

Hi All,
I'm currently fiddling about trying to learn C++ and wrote a little program that outputs the ASCI values for numbers 0-255 but it's got a problem...
For the numbers 255 thru 128 it shows a negative number. For numbers 127-0 (my loop decrements) it shows the correct numerical value...... (6 Replies)
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)
