问题描述

嗨朋友们，



根据班级图表，你能确认我创建的课程是否正确



类图

我的代码：

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:

#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

推荐答案

您已经实现了继承（三角形），但没有实现组合或聚合（钻石） ）。

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

询问Google怎么样？

例如对于聚合和组合： http://en.wikipedia.org/wiki/Object_composition [ ^ ]。

例如继承：http://en.wikipedia.org/wiki/Implementation_inheritance [ ^ ]。

阅读并理解这些内容，然后才开始实施。

干杯

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.

是的。他们是对的。请将方法添加到类图中定义的相应类中。如果您想修改问题，可以更新问题。

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.
