Assistance With Classes (This is to help understand for my Studies - applies to homework)

Gr8Tortuga (2)
I am an adult, very new to programming, and working on a C++ course. We have been growing our assignment from Week 1, where the code we have written continues to evolve based on new learned concepts.

We are currently learning the class concept, and I am honestly having trouble understanding how it applies. I've tried watching videos (Bucky's for example) and doing some reading, but I am just not getting it. I'll place my code below, but please remember 1) I am brand new - I am sure this is not efficient nor is it 100% right, 2) As mentioned this is in support of homework. While this will not give me "the answer" - it will help put me on the right path, and 3) I am very appreciative of anyone who takes the time to help.

My goal is to create a customer class that gets at least the user name and user address. This is in the context of a virtual store, where we sell items, let the customer know what has been purchased and the cost, and thank them.

I have added switch statements to allow for corrections in the address - more as a test to see if I am "getting concepts" than anything. However, that is not required. Please see my code below:

Hi, Gr8Tortuga.
People usually come here to ask for help about specific problems and your question is too vague.
Does your program compile? Does it give you any trouble?

- - -
Just a note.
Let me only suggest you not to spend too time on graphic appearance, since it’s very difficult to get a good one in a textual console: it’s better to focus on the code.
Don’t assume everybody uses a 24" display: try to read or execute your code on a 13" notebook and notice how it looks.
In general, it’s better to remain inside a reasonable line length, let’s say 100-120 characters, to keep the code readable (I’m used to splitting my IDE window in two when I write classes, so I still stick to the old-fashionable 80 characters border). That’s apply both to code lines and console output.
The usage of a backslash ‘\’ to divide string literals is correct, but there’s a far simpler method: just close and re-open commas:

@Gr8Tortuga, classes, conceptually, are for packaging pertinent data together under one roof. All Account-related methods, etc. should be under Account. Perhaps you could eventually create a Store class and encapsulate all the store ideas in there.

Other things to try:
- make an explicit constructor for Account (the compiler automatically made one for you). Initialize "address" and "name" private variables in there. Put a breakpoint to get an idea of when this is being called. Try to then refactor to initialize these same variables using "initializer list" notation, and also put something else in the constructor (e.g. int k=5; k+=1;) put breakpoint on the initializer list and in the constructor to verify which one gets called first.
- make an explicit destructor for Account (the compiler automatically made one for you). As long as you stick with STL structures, you usually won't need to do much here, since they clean up on their own, but for now get a feel for when this is called. In main() do something like { Account k; } , with the extra curly brackets on purpose. An account will be created and destroyed in this scope and you'll be able to see this if you breakpoint inside the destructor (again, write something harmless in there).
- experiment with constructor overloading. Perhaps have both Account() and Account(string address, string name) constructors.

Side note: from what I've seen, private variables are usually written with trailing underscore (e.g. address_ , name_ ). When you have bigger classes, it sometimes helps at a glance to know whether something was public or private, though some modern IDEs are helping out with clever syntax highlighting (at least for locals vs. members).

Google is your friend. Good luck.
