composition relations

Hi Guys,

I want to make a program and in that program I want to make a composition relations.

Eg. I have a class of "Vehicle" and a class of "Bus".

Vehicle class has general data members which are inherited by class "Bus".

But I wanted to know that how can I show composition relations between these 2 classes of "Vehicle" and "Bus"?

eg.

Code:

class Vehicle
{
private :

int regno;
char name;

public:
get int regno();
get char name();

};


class Bus : public Vehicle

{
private:
char buscolor;

public:
get int regno();
get char name();

};

Now how can i show a composition relation between class "Bus" and the "Vehicle"?

Thanks

What is "composition"? Does such a relationship make sense between "Vehicle" and "Bus"?

Of course it does !
Have an open mind.

STUDY A ........ING BOOK!

I can't believe this crap.

Why are you trying to pull a working programming knowledge from the ..... of the regulars at this forum?

You approach is unbelievable stupid. I'm having more trouble wrapping my mind around your level of stupidity than I had with Calculus.

If you'll just read a book you'll find all the answers to these easily searchable questions.

Heck, if you just bothered to read the answers from the four forums you shotgun this crap at you would be significantly less stupid.

That was kind of harsh.

Fair enough in your opinion, but before you hold me to be too harsh read all of his posts.

Not only is he doing himself a great disservice in the approach, he is wasting a lot of time a lot of people donate by asking the same or extremely similar questions over and over on many different forums occasionally at the same freaking time.

Someone, I'm not sure who, has been denied the benefit of the time the regulars at these forums contribute because they wasted it on this individual.

Oh, and I don't even think he is a troll; if I though he was a troll my turn would have been worse but unwritten.
