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;
}
