Can someone point me in the right direction?

[Shannon1981]

I am in my second level of C++ programming. This is the final assignment, and the first time the teacher has made us write a driver.

I have it written(I think). I'd like if someone could take a look. I'll post the program instructions so you know what I am trying to do, as well as the code I have written.

**Yes, I read the homework policy and faq. I don't want anyone to do it for me, just some help, that's all.

Instructions: Program 4: Real Estate Program
You are to create a Real Estate Management Program. The program should allow you to create a list of Commercial or Residential properties, delete properties from the list, print the list to the screen, or save the list to a file. The user should be allowed to run the program until they decide to quit. To implement this program you will need to first implement 3 classes:

Property
member variables:
	    PropertyNumber – a unique 7 digit number to reference the property  
	    Address – street address
	    City, State, ZIPCode
    Stories - number of stories 
	    Condition  - condition of the property (1 - Excellent, 2 - Fair, 3 – Poor)
	    YearBuilt – the year the property was built
	    double MarketValue – the current market value of the property ($)
	    type - 1 for residential, 2 for commercial. No setter needed
member functions:
	Constructors – Optional 
	getters and setters for member variables
	 print() – this function should be overridden by the child classes but can be implemented to avoid redundancy
	 double calculatePropertyTaxes() – this function should be overridden by the child classes for now just return 0
	 double calculateRent() – this function should be overridden by the Commercial class for now just return 0

ResidentialProperty inherits from Property
member variables:
Style - Single-family,  Multi-Unit, SemiDetached, Portable-Dwelling, etc
Bedrooms – number of bedrooms
Bathrooms – number of bathrooms (can have half baths)

member function:
Constructors – Optional. I used it to set the type to its proper value
getters and setters for member variables
print() – override this function to print common and specific info
double calculatePropertyTaxes() – override this function (property taxes for residential property is 5% of market value)

CommercialProperty inherits from Property
Member variables
MaxOccupancy - maximum number ppl that can be in the building
BuildingSize - square footage
RentPerSqFt;  - Rent per sq ft

Member functions:
Constructors – Optional. I used it to set the type to its proper value
getters and setters for member variables
print() – override this function to print common and specific info
double calculatePropertyTaxes() – override this function (property taxes for residential property is 15% of market value)
double calculateRent() – this function uses the building size and the rent per sq. ft to calculate total rent

So what is it you actually need help with? You haven't asked any question here.

Oh yes, sorry! Firstly, the Commercial and Residential classes. More...where do I start? I admit writing classes gives me a bit of trouble(more than a bit). I *think* both should be protected? Beyond that, no real clue...

Let's start there. A beginning skeleton and usually I can fill it in.

Let's start there. A beginning skeleton and usually I can fill it in.

Ok, so write one. They've already told you what you need to put in it.

Start by writing a class that has all of the members they want it to have. Then think about each one, and who needs to be able to access that particular member. Even better, think about what they've given you, and then write it!

Believe it or not, there is actually a decent amount of thinking that goes into writing a program.
