[solved] Check if product is expired

Projects Programming
1

Hello,
I am using the time.h library for getting date.
I need an algorithm or a method for checking if a product has expired but I am loosing it...

I have a product which has an expiration date. For example this date is stored in 3 integers

expDay = 20;
expMonth = 1;
expYear = 2015;

Now I am geting the same type date but the today date

todayDay = day();
todayMonth = month();
todayYear = year();

Also the perfect would be like

todayDate="13-11-2014";
expDate="20-01-2015";

if (todayDate>expDate)
Serial.println("product expired");
How can I implement the if condition ?

todayDate="13-11-2014";
expDate="20-01-2015";

How about

todayDate="20141113";
expDate="20150120";

Can you see the relationship now?

Now yes. All I had to do is to give the write format, sometimes the most simple thing is the solution...
Thank you a lot.
