Hi Friends,

Can you confirm that classes that i have created are correct or not according to Class diagram

Class diagram
https://skydrive.live.com/redir?resid=8B2D8A874799F882!158&authkey=!AGWdCBkmuXTfLLA[^]

my code:


C#
#ifndef PROPERTYCATEGORIES_H
#define PROPERTYCATEGORIES_H


class PropertyCategories
{
    public:
        PropertyCategories();
        virtual ~PropertyCategories();

    protected:

    private:
    string SocietyName;
    int Area;
};


class Plot : public PropertyCategories
{
    public:
        Plot();
        virtual ~Plot();
    protected:

    private:
        int PlotNo;
};

class Flat : public PropertyCategories
{
    public:
        Flat();
        virtual ~Flat();
    protected:

    private:
        int FlatNo;
};


class House : public PropertyCategories
{
    public:
        House();
        virtual ~House();
    protected:

    private:
        int HouseNo;
};







#endif // PROPERTYCATEGORIES_H





>NOTE: I don't need to implement this code into the program.

You have implemented inheritance (triangle), but not the composition or rather aggregation (diamond).

how to implement composition or aggregation

You basically create an object of a class as a member of another class.

you mean my 2 last classes are incorrect according to diagram?

They are correct, but incomplete. They do not have a member object.

yup ..... I have added members only now plz check are they correct only members not added methods yet(question Updated)
How about asking Google?
E.g. For Aggregation and composition: http://en.wikipedia.org/wiki/Object_composition[^].
E.g Inheritance: http://en.wikipedia.org/wiki/Implementation_inheritance[^].
Read and understand these, then only start to implement.

Yes. they are right. Please add the methods to the respective classes as defined in the class diagram. you can update questions if you want to modify your question.
