C++中的简单继承

Father.cpp:

#include<iostream>
using namespace std;
class Father
{
protected:
    int width;
    int height;
public:
    void setWidth(int widths)
    {
        width = widths;
    }
    void setHeight(int heights)
    {
        height = heights;
    }
};

class Son : public Father
{
private:
    int weight;
public:
    void setWeight(int weights)
    {
        weight = weights;
    }
    void show()
    {
    cout<<"width ="<<width<<"	"<<"height="<<height<<"	"<<"weight="<<weight<<endl;
    }
};

int main()
{
    Son a;
    a.setWeight(100);
    a.setHeight(180);
    a.setWidth(70);
    a.show();
    return 0;
}
