Question
use c++ to write this program
This system of programs implements and tests a class that encapsulates various functions related to dates. He are the specifications 1. Store the month, day, and year in separate private integer variables 2. Your My Date class will have two constructors. The first one takes no arguments and sets the date to March 27, 2017. The second takes a string in the form MM/DD/YYYY and sets the date to that 3. Provide accessor functions for the month, day, and year. The mutator functions do not do error checking, since that is beyond the scope of this assignment. Your driver program, described below, will do limited error checking 4. Provide a function called SetDate that takes a string in the form MM/DDYYYY and sets the new date. This will return true if the date is valid and false if it is not. However, you can assume that the string will always be in the correct format, with slashes between the components. For example, the function should return false for 3/32/2017 5. Provide a function ToString that takes no parameters and returns the date as a string in the form MM/DD/YYYY 6. Provide an add function that takes an integer as its parameter and adds that number of days to the given date. It returns a string in the form MM/DD/YYYY with the new date 7. Provide a subtract function that takes an integer as its parameter and subtracts that number of days from the given dateExplanation / Answer
