The class dateType defined in Programming Exercise 6 prints the date in numerical form. Some applications might require the date to be printed in another form, such as March 24, 2003. Derive the class extDateType so that the date can be printed in either form. Add a data member to the class extDateType so that the month can also be stored in string form. Add a function member to output the month in the string format followed by the yearfor example, in the form March 2003. Write the definitions of the functions to implement the operations for the class extDateType.

Programming exercise 6:

cout << "Enter Month as a number:";

cin >> m;

cout << "Enter Day:";

cin >> d;

cout << "Enter Year:";

//create a new date as follows

//month=3,day=18,year=2017

//Then set 25 days to add to the date

//result date is month=4,day=12,year =2017
