Chapter 9, Problem 9.19E

(Date Class Modification) Modify class Date in Fig. 9.18 to have the following capabilities:

1. Output the date in multiple formats such as
DDD YYYY
MM/DD/YY
June 14, 1992

2. Use overloaded constructors to create Date objects initialized with dates of the formats in part (a).
3. Create a Date constructor that reads the system date using the standard library functions of the header and sets the Date members. See your compiler's reference documentation or http://en.cppreference.eom/w/cpp/chrono/c for information on the functions in header . You might also want to check out C++11’s chrono library at http://en.eppreference.com/w/cpp/chrono.

In Chapter 10, we’ll be able to create operators for testing the equality of two dates and for comparing dates to determine whether one date is prior to, or after, another.
