Question

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, 2019. Derive the class extDateType so that the date can be printed in either form.

Add a member variable to the class extDateType so that the month can also be stored in string form. Add a member function to output the month in the string format, followed by the year—for example, in the form March 2019.

Write the definitions of the functions to implement the operations for the class extDateType.

Note: you may write a main.cpp to test your class but will not be graded on the main.cpp.

I do not have/need main.cpp, I am needing extDateTypeImp.cpp.

I have dateType.h, dateTypeImp.cpp, extDateType.h.

dateTypeImp.cpp:
