So what are the errors that you have ?

i think i repost my programme with errors stated:

err.. acutually now left last 3 errors only ,the rest solved,thanks

Hi cnmsg007

Please try to explain whats your so I can help all some of your is

class Set_Nnum : public NomineeData  //Derived from class MemberData to assign no to nominees
{
private:
    char "James Tan", "Benny Koh", "Steven Lim", "David Tay", "Mary Tan";
public:
    void Setname(void);
};

what is this? How can you define variable like this read book carefully how to create variable, rulation and regulation of creating variable and then try to resolve your problem.

yeah, i found that,thank you.

Looks Like this code is not yours or you don't have a clue about it, because you cannot spot simple mistakes, the errors are guiding you to your mistakes.

You have some problems in the declaration of enum
and then the two function the compiler is highlighting both of them takes "an int and a char" as inputs in order to make them work.
