Instructions In this chapter, the class dateType was designed to implement the date in a program, but the member function setDate and the constructor do not check whether the date is valid before storing the date in the member variables. Rewrite the definitions of the function setDate and the constructor so that the values for the month, day, and year are checked before storing the date into the member variables.

In this chapter, the class dateType was designed to implement the date in a program, but the
member function setDate and the constructor do not check whether the date is valid before
storing the date in the member variables. Rewrite the definitions of the function set Date and the
constructor so that the values for the month, day, and year are checked before storing the date
into the member variables. Add a member function, isLeap Year, to check whether a year is a
leap year. Moreover, write a test program to test your class.
Input should be format month day year with each separated by a space. Output should
resemble the following:
Date #: month-day-year
An example of the program is shown below:
Date 1: 3-15-2008
this is a leap year
If the year is a leap year, print the date and a message indicating it is a leap year, otherwise print a
message indicating that it is not a leap year.
The header file for the class dateType has been provided for you.
