how many days in each month?

Expand Post »
Anyone know how I can tell how many days are in each month? A formula would be really nice.

Re: how many days in each month?

For non-leap years, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31. For leap years, add one to February using the formula:

((year MOD 4 = 0 AND year MOD 100 <> 0) OR year MOD 400 = 0)

Thanks! Now I just need to find some cool things to do with dates!

How about a program that can unravel the mess?

Re: how many days in each month?

I'm trying to do something that will help me learn a little. I know all the easy stuff but I can't find anything to do with pointers and references. I have add and subtract functions, but none of those require me to use references or points

Re: how many days in each month?

Do you want to learn about time and date programming or about references and pointers? You would be better off playing with some high level data structures for the latter.

Re: how many days in each month?

I don't really care about date/time programming, but I just wanted to start a program that could possibly give me some good experience. I'm most interested in getting more experience with pointers and references, so I thought I could implement something in the date class I was making, but was wrong.

See, the two functions I have return dates, because that seems to be the most sensible approach:

Date Date::add(Date addThis)
{
}

At first I was hoping for a function that used references or pointers, but it would turn out messy, and kind of stupid:

void Date::add(Date addThis, Date &ref)
{
}

The only way I could think of using references was to provide a second paramenter, which seems like a terrible solution.

I hope you see what I'm getting at even though I don't write very clear!
Anyways, I'm reading three different books and got more than enough experience with refs and pointers with in text reading, but I want hands on experience. I just can't seem to find something useful to do. I mean, almost everything I think can be done returning the object rather than using a reference.

Any of that make sense!

Write a balanced binary search tree. That will give you plenty of experience with pointers. See below for a recommendation to get a handle (pun intended) on references.

>which seems like a terrible solution.
Probably because it is.

>I mean, almost everything I think can be done returning the object rather than using a reference.
Create your own stream. You'll be forced to use references heavily.

Re: how many days in each month?

Thanks Narue!
I believe I'm going to try the binary search tree first. It won't be till this weekend, but look around for me in the ++ forum, just in case I have problems
