Chapter 11 Programming Exercise #9

Using the classes extDateType (Programming Exercise 8) and dayType (Chapter 10, Programming Exercise 5), design the class calendarType so that, given the month and the year, we can print the calendar for that month. To print a monthly calendar, you must know the first day of the month and the number of days in that month. Thus, you must store the first day of the month, which is of the form dayType, and the month and the year of the calendar. Clearly, the month and the year can be stored in an object of the form extDateType by setting the day component of the date to 1 and the month and year as specified by the user. Thus, the class calendarType has two member variables: an object of the type dayType and an object of the type extDateType.

Design the class calendarType so that the program can print a calendar for any month starting January 1, 1500. Note that the day for January 1 of the year 1500 is a Monday. To calculate the first day of a month, you can add the appropriate days to Monday of January 1, 1500. For the class calendarType, include the following operations:

a. Determine the first day of the month for which the calendar will be printed. Call this operation firstDayOfMonth.

b. Set the month.

c. Set the year.

d. Return the month.

e. Return the year.

f. Print the calendar for the particular month.

g. Add the appropriate constructors to initialize the member variables.

Here is what the output should look like:

Prior to this, I have completed some programming exercises that had led up to this exercise which granted me the output(without completing P.E. #9):

I am wanting to figure out how to get the 1st image's output as I am currently working out my definitions of my setdate.h file while removing any errors.

I have provided the code below.

Note: I Intentionally left dateTypeImp.cpp untouched when the error displays that it was already defined. The problem is what arises when you remove these excess redefinitions as more errors become apparent with the definitions.

Note: Please actually help me on this and not just create a new program answering the programming exercise question while disregarding the provided code.

I can post my previous code before my attempt with this exercise if need be.
