No clue where to start: Real Estate Program

Question

So there’s a challenge in a book I’m reading and I have no clue where to begin with this. Any help would be appreciated.

Imagine you are investing in real estate and need to create a program to help track, estimate and/or
manage costs related to a real estate property.

Create the following private member variables:
1. property name/identifier
2. home sale price
3. HOA (home owners association) monthly cost
4. number of bedrooms
5. number of bathrooms
6. house square feet

• Create accessor/mutator (get/set) functions for each member variable. Ensure that you use
“const” where necessary. The property name is a string, so for the mutator/set function, the
input parameter should be a reference to a string constant.
• Create two constructors: one which does not take in any input parameters and assigns the
numeric variables to 0 and string variables to empty string. A second (overloaded constructor)
which takes in parameters for each variable and assigns the values passed in to the member
variables.
• Create a toString() method that returns a string which prints out all of the variable values of the
this RealEstateProperty class. When calling this toString() function, the price per square feet
should also be printed along with the other variable values.
• Create a function named calculateMortgage() which calculates the mortgage monthly payment.
The mortgage monthly payment (M) of a property is calculated as follows:
𝑀 = 𝑃
𝑟(1 + 𝑟)^n/
(1 + 𝑟)^n- 1
This function should output the monthly payment (M) and should have the following input
parameters: down payment and monthly interest rate. Assume you will be paying the loan for
360 months. **Hint: use the Math library for exponent computation

Answer 1

Where do you have problems?

--> create a class/object
--> insert all needed variables
--> insert the two constructors
--> insert setter/getter for each variable
--> insert all methods you need

Start with the stuff you know.

Answer 2

(In java it is called setter and getter, sorry if I have confused you)

Answer 3

Can you post your code here on sololearn? (using the code playground)

Answer 4

https://docs.microsoft.com/en-us/cpp/cpp/header-files-cpp?view=vs-2017

Answer 5

The second part of your question: I think this what sneeze has written: "in your main class
--> create a instance of your realEstate class"

header file
realEstate.cpp (realEstate class)
main.cpp (main class, include header file, instance of realEstate class)

Answer 6

Now fill your realEstate with life. And implement the toString() method. So you can easily test your class.

Answer 8

Charlie But in principle, it's written like an instruction manual that you can work through step by step.

Answer 9

Charlie Yes. 6 setFunctions and 6 getFunctions.

Answer 10

Create a class that you call "realestate".

Create a property in that class that is called "property_name"
Make a property and private variable.

In you main program
Create a instance of your realestate class
Assing a name to the "property_name"

And print the name to the console.

Hope this will get you started. Keep coding

Answer 11

I have an issue with the wording I guess, its a bit whelming.

Answer 12

ive done the private member variables. how can i make a accessor/mutator function?

Answer 13

So would I need to make set/get functions for every variable?

Answer 14

it tells me “the header file should declare the class and its private member variables and member function prototypes/declarations.” what does that mean?
also what does “The RealEstateProperty class function defintions should be implemented in a seperate .cpp”?

Answer 15

thats part of the original question, i couldnt fit it since its quite big, I get that i need to declare a class in a header file. I also know i put the variables there, but im wondering if the set/get functions are include in the header file or in the .cpp file

Answer 16

ive made a main.cpp, RealEstateProperty.cpp and RealEstateProperty.h

Answer 17

how would i go aboht making the toString() method?
