构造函数的执行顺序

#include<iostream>
#include<string>
using namespace std;
class Demo
{
    public:
        Demo(string s);
        ~Demo();
    private:
        string m_s;
};
Demo::Demo(string s):m_s(s){}
Demo::~Demo(){cout<<m_s<<endl;}
void func()
{
    Demo boj1("1");
}
Demo obj2("2");
int main()
{
    //局部对象
    Demo obj3("3");
    Demo *pobj4=new Demo("4");
    func();
    cout<<"main"<<endl;
    return 0;
