class A{
public:
A(){ cout << "this is A" << endl; }
~A(){ cout << "delete A" << endl; }
};
class B{
public:
B(){ cout << "this is B" << endl; }
~B(){ cout << "delete B" << endl; }
};
class C :public B, A {
public:
~C(){ cout << "delete C" << endl; }
C(){ cout << "this is class C" << endl; }
};
int main()
{
C temp;
return 0;
}
运行结果为：
this is B
this is A
this is class C
delete C
delete A
delete B
1、C调用B，A的顺序是 由继承中声明的顺序决定的。
public B ，A； // 决定了先构造B，然后A
2、先调用父类的构造函数，然后再调用子类的构造函数
3、析构时先析构子类，再析构父类
