help to design class diagram
 

Hi to all


I want to know how to relate classes in c++.

For Ex:

My project is to get the system information like monitor, cpu, os , network..

So how can i design a class diagram.. which 1 is good among following

1.take computer as base class , and monitor , cpu, os as derived class.

2. Take computer as base class and treat Monitor cpu, OS as agregates of Computer..


And one more question

How can i implement if i consider any one among above.


How to upload a diagram to this forum..
sori for bad english

One of the best (if not only) ways to get help with homework - not that I have anything against helping people with their homework - is to show us some of the work you have already done.

As far as uploading a diagram, I suggest uploading the file to some personal web space (if you have some, that is) and just posting a link.

Your other threads don't sound like homework. So I don't know how to react to this one that does.

When you try to model physical reality with object oriented inheritance you are looking for "is a kind of" relationships. So "computer" as base class for "monitor" would make sense if "a monitor is a kind of computer". You can't intend that, and I can't think of anything else you might intend with computer as the base class for monitor.

Did you mean computer_part as the base class?

It's even harder to figure out how that is supposed to make sense.

A computer might be an aggregate of computer_parts.

I haven't looked at the source code for the open source project lshw. But it seems to be available easily. A web page on that subject says it is C++ code. It takes a very structured approach to reporting the characteristics of computer components. So it might be a good example to look at. There is a clear advantage to looking at the work of someone who did a good job at a similar task, rather than asking the random opinions of those who might reply to a thread like this.
