How do i write program in C++ to check if a date is before April 5,2008?
I have this if statement:
if(month<=4||day<5&&year<=2008)
but it is not evauluting day correctly. What i am trying to do is see if a date (from a file) is before april 5,2008. I am reading month and day separately.
Does anyone know how to code this?
I would use the <ctime> functions and convert to a time_t and do a direct comparison.
This is what you want I believe:
The reason for the extra bits is that day < 5, for example, is meaningless on its own as the year or month could be anything.Code:if (year < 2008 ||
(year == 2008 && month < 4) ||
(year == 2008 && month == 4 && day < 5))
It can be shortened slightly by combining the two year == 2008 bits, but then you'd probably find it slightly harder to understand.
umm im not sure what that means. Can you give me an example in this case.
oh, wow that would work
thanks.
could it not be
? Or maybe I am just having serious logic problems today.Code:if ( year <= 2008 && month <= 4 && day < 5 )
Logic problem day....
if the year is less than 2008
OR
if the year is 2008 but the month is earlier than April
Or
if the year is 2008 and the month is April, bu the day is before the 5th.
I.e. The problem with your code is that if the date were December 25, 1999. The statement would fail.
If the date passed is Nov 20, 2007, that will fail (on the month and day test)Quote:

Well Todd's example wasn't quite as Christmassy as mine... Nor does he seem to want to party like its 1999......
if(x > 62 && x < 115)
Why do so many C programmers and Java programmers not put a space between the "if" and the "("?
Todd
Java was the first real language I learned.... and C would be numero dos... So maybe that is why for me. I don't now... I just don't like putting a space there.
Hohoho
haha, i see my stupidity...
I am glad you have found yours. I am still endlessly trying to find mine... much to no avail.Quote:

It's always there, we just tend to be blinded by our greater moments...
edit: of course... I haven't been in the club yet :D
Heh... Elysia says I should be more serious, however if I were more serious I probably would never make it into the club. Today I am tired and not feeling like I have much to offer in the way of great moments though. I need to hurry up so I can go home and take a nap.
