Debug my program

Thanks.  Tonight I'll check your answers

You wrote ... I'd leave the code in ...
Could you complete this sentence?
You may always reply by e-mail

Below you find an assignment with its solution.
There are still 3 errors, ( I indicated them with //?? and a description ),
could you correct them?
Could you adjust  the program so the program asks in case 3 (3. Retrieve
all data) for the name of the student from whom you want to retrieve the
data?
Is this a good solution?


Assignment:


      Develop a class where the following data is                 kept:
            +name student
            +street
            +zipcode
            +city
            +course (number, title, number of                                  hours); the number of courses is not
             known in advance

      Next seperate member functions must be used:
            +input of the personal data
            +addition of a course; courses must be                                    kept in a binary tree
            +retrieve all data; courses must be                                          shown in the sequence of their
             course number

Solution:
