C++ Share Interface Problem

Hi Everyone, I'm back!!!!:D. My computer has given up the ghost, so I am
writing this in the net cafe, in the hope of getting some desperatly
needed help. I know you guys and gals don't usually help with assignments but any help would be appreciated.

My problem here (like many others) is that I am not entirely sure how to
start this process.

What I am trying to do is create a program for maintaining a table of
shares that has some or all of the following features.

1. It should have a means by which the user can inspect information
on an individual share.

2. It should have a means by which the user can edit and save
information on an individual share.

3. It should have a means of adding details on a new share to
the table.

4. It should have a means of displaying a list of all the shares;
for each entry in the list the name and current price of the
share should be given.

I am trying to develop an interface using the provided engine. I am using Borland Builder V5

Code:

---

//---------------------------------------------------------------------
#ifndef ShareEngineH // written in header file.

#define ShareEngineH // written in header file.
//---------------------------------------------------------------------
Struct ShareType
{
  AnsiString Name; // The identifier of the share.
  int Now; // The current price per share.
  int High; // The highest price of the share in the past 12 months.
  int Low; // The lowest price of the share in the past 12 months.
};
class ShareTableType
{
private:
  // Not Shown here.
  // An object of this class represents a table
  // containing information on up to 100 shares.
  ShareType Shares[101]; // written in header file.
 
  int LastFound; // written in header file.

public:
  void Initialise(void);
    // Initialises the table of shares which are indexed from 1 to 100.
    // Empty entries are given value " " for Name.
  ShareType GetShare(int I);
    // Returns the information on share at index I.  If I is an
    // inappropriate value the dummy share with name "*" is returned.
  ShareType FindShare(AnsiString TryName);
    // Returns information on a share with name TryName, if such exists.
    // Otherwise returns the dummy share with name "*".
  bool NewShare(ShareType Addition);
    // Records the details of the new share (Addition), provided there
    // is room available.  Returns true if there is room; false otherwise.
  void EditedShare(ShareType Updated);
    // Records the revised details of a share.  This method must be used
    // with GetShare as it is the last record found by GetShare which will
    // be updated.
};

endif // written in header file.

Any Help/guidance will as always be greatly appreciated.
