编程学习网为您整理以下代码实例，主要实现：C++基础和派生类，希望可以帮到各位朋友。

#include <iostream>

using namespace std;

// Base class
class Shape {
   public:
      voID setWIDth(int w) {
         wIDth = w;
      }
      voID setHeight(int h) {
         height = h;
      }

   protected:
      int wIDth;
      int height;
};

// Derived class
class Rectangle: public Shape {
   public:
      int getArea() { 
         return (wIDth * height); 
      }
};

int main(voID) {
   Rectangle Rect;

   Rect.setWIDth(5);
   Rect.setHeight(7);

   // Print the area of the object.
   cout << "Total area: " << Rect.getArea() << endl;

   return 0;
}
