(The Date class) Design a class named Date. The class contains:

■ Data fields year , month , and day that represent a date.

■ A no-arg constructor that creates a Date object for the current date.

■ A constructor that constructs a Date object with a specified elapse time since the middle of night, Jan 1, 1970, in seconds.

■ A constructor that constructs a Date object with the specified year, month, and day.

■ Three get functions for the data fields year , month , and day.

■ A function named setDate(int elapseTime) that sets a new date for the object using the elapsed time.

Draw the UML diagram for the class. Implement the class. Write a test program that creates two Date objects, one using a no-arg constructor and the other using Date(555550) , and display their year, month, and day.

(Hint: The first two constructors will extract year, month, and day from the elapse time. For example, if the elapse time is 561555550 seconds, the year is 1987 , the month is 10 , and the day is 17. For the no-arg constructor, the current date can be obtained using time(0) , as shown in Listing, ShowCurrentTime.cpp.)
