Python

PART 1:

Define a class to implement the date type as an ADT based on the following description: 1. This class has three integers as attributes: day, month, and year. Here are the constraints on

these attributes:

1?month?12

1 ? day ? 31 for the month numbers 1, 3, 5, 7, 8, 10, and 12. if month = 2 then 1 ? day ? 28, and

1 ? day ? 30 for all other months.

year ? 1900

The initializer method of this class initializes the date object with a date passed as the argument. In case that no argument exists, or an invalid argument is passed the date is initialized as 1/1/1900.

Define a method in your class to return the name of the month of the object.

Define a method to validate a day number based on a month number. This function returns

True if the day is a valid day in that month and returns False otherwise.

Define a method to move the date a specific number of days forward. For example, moving the

date 1/1/2018, 20 days forward changes the date to 21/1/2018.

Define a method to move the date a specific number of days backward. For example, moving

the date 1/1/2018, 3 days backward changes the date to 29/12/2017.

Define a method to calculate the difference between the date and another date in days.

Define a method to return the next date.

Define a method to return the previous date.

Define a method to display the date in the format dd-mm-yyyy on the screen.

Notes:

Do not consider leap years.

For each attribute and method decide if the member should be private or public. For the

private attributes, provide getter/setter methods.

PART 2:

Use the date class to write a program that asks user to enter the current date and his/her date of birth, then compares the users date of birth with the current date and prints a happy birthday message if they are equal. In case the current date is different from the users birth date, this program displays its next birthday in the format of dd-mm-yyyy along with the number of days remained to that date on the screen.
