一个月学习C++笔记(七)

C++ 继承
C++允许为一个派生类指定多个基类，这样的继承结构称作多重继承

#include <iostream>using namespace std;class Vehicle{public:Vehicle(int weight=0){Vehicle::weight=weight;}void SetWeight(int weight){cout<<"chong xin she zhi zhong liang"<<endl;Vehicle::weight=weight;}virtual void ShowMe()=0;protected:int weight;};class Car{public:Car(int weight=0,int aird=0):Vehicle(weight){Car::aird=aird;}~Car();/* data */};
