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<<"\t"<<"height="<<height<<"\t"<<"weight="<<weight<<endl;
     }
 };

 int main()
 {
     Son a;
     a.setWeight();
     a.setHeight();
     a.setWidth();
     a.show();
     return ;
 }
