My issues (I have a lot but for the sake of time):

1. I have no idea how to make the bool “IsLeapYear” work and add 1 Day to March to represent a leap year

2. For “readDate” I don’t know how to put a limit on the days in the months. Ex: April has only 30 days but the user can put 31 and no error shows up.

3. Also I may not see it but I want to know if the bool Isleapyear accurate in calculating a leap year.
