Hi there,

I'm having some trouble with the display function in student, instructor and
programmer classes.

                   void display(char *);
                      This function is passed a pointer to a
                      character string, and the function writes the
                      information about the person into that string.
                      The format of the information can be seen
                      in the sample program: in the display of people
                      in the list, each line is the string returned
                      by this function.

As stated above, display function in student class should return a string
like "STUDENT: Yihang Tang(CMPT)", right? How can I append several strings
into one single string? Any predefined function in string.h will do this
job?

Thanks for your help.

Regards,

Yihang
