So what error messages are you getting when you try to compile this program?

This is what the C++Shell (press the gear to the right of your code) compiler says:

In function 'void outputToFile(std::string, std::string, std::string, float, double, char)':
145:10: error: expected unqualified-id before '.' token
146:10: error: expected unqualified-id before '.' token
166:45: error: 'teamMemberAmmount' was not declared in this scope
171:33: error: 'invoiceTotal' was not declared in this scope
In function 'int main()':
212:8: error: 'class invoice' has no member named 'outputToFile'
212:21: error: 'clientName' was not declared in this scope
212:33: error: 'teamMemberName' was not declared in this scope
212:49: error: 'titleName' was not declared in this scope
212:60: error: 'hoursWorked' was not declared in this scope
212:73: error: 'payRate' was not declared in this scope
212:82: error: 'userResponse' was not declared in this scope

You're really not using the class since neither outputToFile() nor outputToConsole() are class member functions.

So I've modified this program to use class and main in different files but right now I'm getting a error: lnk2019 unresolved external symbol. Here is my three files if anyone can give me an idea on whats wrong

What does the whole error message say? Usually it gives an indication of the function or class it can't find.

Have you incorporated the header files in the project? A linker error occurs if you haven't.

What this means is the linker can't find the files with those two functions ie unresolved externals.

It looks like you are using VStudio so what you need to do is add the files to your project. You can do this by going to the Project menu and selecting Add existing item

So my ifndef was not in all caps I fixed that and now I have this error.

I'm assuming the error is in main on line 157 but im getting these errors

You have serious naming problems. Bluntly ...

1. You want to get rid of naming your files and variables with silly names, they are too long and meaningless.
2. Amount has a single m.
3. getMemTotal etc are stupid names, use getTotal etc
4. Your class is Invoice, not the AndrewSmithProjectThreeClass :: absurdity
5. The class prototypes must be compatible with their implementation, parameters AND return values. Swapping parameters around and returning a double from a void method doesn't work!

That's a start.

PS Why use Notepad++, it's crap, especially for beginners.



Andrew655 (25)
Granted my naming conventions are a little more descriptive then most but as a beginner descriptiveness is the lest of my worries and also you can name a variable anything you want that is not why my program is not working. Thanks for the other tips I will continue to research and learn what I can.

You also don't have an Invoice constructor!

Once you fix up those problems and remove and reload the files into the project you will find it runs. Until you do those things you are going to continue spinning your wheels.

"ridiculously_long_and_stupid_name.cpp" Definitely my favorite part!! But thank you the other stuff, it has helped. I have began reading more on it and I will try in the future not to use long names.

I assume this last post of yours means you still can't get it to run.

The code I posted here runs without linker problems with Visual Studio 2015 by manually adding the 3 files to a blank project using the menu items I referred to before.

This is the partial output in the cmd.exe box


Please enter your clients name: Andrew Long

Thank you Andrew Long Now please have your team member information ready!
OK lets get started!

Please enter the team member's name: Silly Name

Thank you!

Now please select the team member Silly Name's job title from the following
Type A: for Project Manager
Type B: for Network Administrator
Type C: for Network Analyst
Type D: for Network Design Engineer
B

Please enter the amount of hours Silly Name worked. Then press enter:

Granted my naming conventions are a little more descriptive then most but as a beginner descriptiveness is the lest of my worries and also you can name a variable anything you want that is not why my program is not working.


I just noticed this piece of rubbish. Many people come here, and I am not a gatekeeper, are in denial just as this example demonstrates.

Good programming requires common sense and discipline. It's not magic.

Your names are ill-considered, too complicated, badly spelt and often meaningless, anything but descriptive. I am the only person who has taken a genuine interest in your unsuccessful efforts and solved your problem for you. All you want to do is argue the point, whine and not follow the advice that gets you out of the hole you have made for yourself. That doesn't make sense to me.

So the reason your are here is to try to discourage people who are new to programming? I have learned some things from you but your attitude is less than appealing and not how you help people. If it is such a bother to you please don't reply as I will do my best to avoid anything else you say. Thanks for the help and have a happy Thanksgiving (if you can ^.^)

You're beautiful when you're angry Andrew. I've reported you for being immature and throwing a tantrum because you have trouble accepting sound advice.
