OOP nightmare!

I wants to store the details of employees in an electronic format (name, address, title, telephone number and date of birth). I system to allow for updating the details as well as adding or deleting employees.

I want to do the followings:

1. Identify the various elements of this system using an object-based design and clearly identify classes, attributes and associated methods from the above specification.

2. Produce an object-based design linked to the scenario described in the brief.


I decided to improve the system so that it includes the students, academic and administration staff of each department. The system should be able to show the qualifications, schedule and courses of each lecturer is working on. Also, it should be able to show the ID and the course each student has registered on.

A lecturer can lecture on different units of different courses.

Students can enrol on different part time courses but only one full time course.

I want to to this:

3. Modify my design to take into account the above improvements.

I wants to improve the system so that it is possible to store the details of students on a waiting list in a queue.

4. I would like to Produce an additional modification that will establish a queuing system that allocates places on a first come first served

Where are you having the problem?
[I trust you don't expect someone else to write it for you]

Are you getting any errors?

In the future, when posting large amounts of code, its easier to post a file than to post the code directly... additionally, when posting small snippets of code, use the [ code][/code ] tags for formatting (without the spaces)

i'm stuck with "designing the Boxes before doing the actual coding" and plus saving the employee details. in the " void main()" i'm thinking about using Switch statement but I don't know how to go abou it!

This is far from an OOP nightmare, but more of a great exercise to get you used to using objects...

Why not create a single class, like a person class... then create others which extend it (for students, academic and administration staff of each department)

The "parent" class, i'll call person, would contain any information which is common amongst all the different classifications of "employees"/people... such as name, address, title, telephone number and date of birth... each extended class, or child class, would then contain information specific to that type of person... a student may have grades, a teacher may have a pay scale...

Remember, for each attribute/variable inside an object, it helps to have methods which set and get them...

In your main then, you would have to declare each unique object and use the set methods to set their variables...

Simple pseudo code based on one person would look like this:
jeff = new Student()
jeff->setName("Jeff Jefferson")
jeff->setAddress("123 Fake St")


I hope this helps a bit...

I searched quickly, but couldn't find a C++ article... There's a lot of general OOP beginners articles out there if you Google for 'em...

In the meantime, try reading this Java one... Hope it helps:

Thank you! I get the idea now.
