Question

C++设计一个子类继承多个父类，谢谢；

设计一个子类继承多个父类，要求在main函数中创建子类对象，掌握子类对象对父类构造函数的调用次序以及析构次序

Answer 1

class A
{
public:
A(){cout << "A Constructor!" << endl;}
~A(){cout << "A Destructor!" << endl;}
};

class B
{
public:
B(){cout << "B Constructor!" << endl;}
~B(){cout << "B Destructor!" << endl;}
};

class C:public A, public B //基类的构造函数按照继承时声明的先后顺序从前到后执行，最后执行自己的构造函数；析构函数则按照相反的顺序执行。
{
public:
C(){cout << "C Constructor!" << endl;}
~C(){cout << "C Destructor!" << endl;}
};

int main()
{
C c;
return 0;
}
