This what I have done so far... (to cscgal and inscissor) As you can probably tell I have't done C++ for long; only a few weeks now so please point out any mistakes that I have made. Here is some evidence to prove that I have tried, even though it isn't perfect, I am pleased with it because it is one of my first proper programs... Due to the fact that I have demonstrated that I have done some of the code (And by the way, I didn't pay anyone to write it for me from rentacoder.com even though if I need to have something coded that is beyond my cababilities, I will use that website so thanks for the link inscissor!)
I have had a few problems with this application ... For instance, I know that I have to include the 'string.h' library file but whenever I try and compile the code, I get an error saying that the file/directory can not be found. Any help with this?
I also need to add three other classes - an application class which can be used as the entry-point into the application: CApplication, Two derived classes to split the information about the 'individual' into details about themselves like their name and event dates for example; and another class to gather information about their business, if they have one like, for example, their company name.
The code that I have put 'debug' by obviously means that it needs debugging when something happens during the program that shouldn't. I am mentioning this because that code is ok, even though it needs correcting - its to show that flaws of this application i.e what it can and can't do.
As you might have realised... this code won't actually work - don't worry! its not supposed to! I just have to demonstrate that I can use classes and be able to handle data. Unfortuanately, because of this, I don't know if the seperate parts of it work so if someone can tell me if they think it looks ok, I will be grateful!
