i am working on reminders/to do list program i am not able to get the dates in required format.
You don't seem to have the data structures necessary to support a to do list with reminders. Once you sort out your data structures, you'll discover you need a data/time class to do all the conversions.

We can help you along the way, but you're not headed in the right direction.

hmm sorry didnt get you .

Look at this http://www.cplusplus.com/reference/clibrary/ctime/ctime/

There're a lot of function to deal with date/time. Like strftime http://www.cplusplus.com/reference/clibrary/ctime/strftime/ which is similar to printf just for formating date/time.

struct tm http://www.cplusplus.com/reference/clibrary/ctime/tm/ already contains the members (and more) of your class date. Better use that struct and don't forget to set the unused members to 0.

can i write this program without using strftime / ctime in C++ ?
