Create two different implementations of a class called Date. Each implementation

Question

Create two different implementations of a class called Date. Each implementation should provide the following functionalities: two constructors: i. A default constructor that initializes the date to 1/1/1900. ii. A constructor that accepts three arguments: a month (type int), a day (type int) and a year (type int) to initialize the object instance. The constructor assumes that the day value should be from 1 to 31, the month from1 to 12 and the year is between 1900 and 2025. a getMonth, getDay and getYear methods (these are accessor methods). a setMonth, setDay and setYear methods (these are mutator methods). Each of the three methods takes an integer as an argument and assumes that the value provided fall under the correct range. a display method that prints to the standard output the month, day and year separated by forward slashes (/). an == operator that takes another Date object as an argument. The method will return true if the date of the object instance is equal to the Date objects that is sent as an argument, otherwise the method returns false. a. The first implementation (called Date1) should use three member variables—a month (type int), a day (type int) and a year (type int). The interface and the implementation should be in separate files (.h and .cpp respectively). b. The second implementation (called Date2) should use one member variable—a string that stores the month, day and year separated by forward slashes (/). The interface and the implementation should be in separate files (.h and .cpp respectively). The main( ) method should demonstrate the capabilities of both implementations of the Date class. First, main should create an instance of each implementation then should make sure that each member function is working properly
