Initializing with constructors

[bradmanda]

Hello, I need to figure out how to add a constructor and destructor to my class, labeled "Invoice." The constructor will initialize the invoice number (innumber) to 1000, days (days) to 1, category (categ) to 2, and the insurance (insur) to 0.0. I don't believe I can just simply initialize the values in my external member functions below like so, because I keep getting the following error prompts. Any help is appreciated!


d:\projects\invoice5.cpp(24) : error C2614: 'Invoice' : illegal member initialization: 'categ' is not a base or member
d:\projects\invoice5.cpp(24) : error C2614: 'Invoice' : illegal member initialization: 'insur' is not a base or member
d:\projects\invoice5.cpp(24) : error C2614: 'Invoice' : illegal member initialization: 'days' is not a base or member
d:\projects\invoice5.cpp(24) : error C2614: 'Invoice' : illegal member initialization: 'innumber' is not a base or member

Use [ignore]

[/ignore] tags when posting code.

The only member variable you have in your class is data, so the compiler is telling you it doesn't know what you're talking about.
You need to initialize each of the members of your data member.
