类与对象-继承-构造和析构顺序

构造和析构顺序

#include<iostream>
using namespace std;

class Base
{
public:
	Base()
	{
		cout << "Base构造函数" << endl;
	}

	~Base()
	{
		cout << "Base析构函数" << endl;
	}
};

class Son :public Base
{
public:
	Son()
	{
		cout << "Son构造函数" << endl;
	}

	~Son()
	{
		cout << "Son析构函数" << endl;
	}
};
void test01()
{
	Son s;
}
int main() {
	test01();

	return 0;
}

结论：
继承中先调用父类构造函数，再调用子类构造函数，析构顺序与构造顺序相反
