这是我试图理解其输出的代码。
class A
{
public:
A();
~A(){ cout<<"Destructor Called from A"<<endl;}
A(int x):Z(x){ cout<<"Constructor Called from A"<<endl; };
private:
int Z;
};
class B:public A
{
public:
B();
~B(){ cout<<"Destructor Called from B"<<endl;}
B(int x):A(x),Y(x){ cout<<"Constructor Called from B"<<endl; };
private:
int Y;
};
int main() {
A *a = new B(10);
delete a;
return 0;
}
我得到的输出是
Constructor Called from A
Constructor Called from B
Destructor Called from A
我的问题是，B 类的析构函数发生了什么？
对象切片在这里发挥作用吗？
