[c++]怎麼樣知道解構函式先後的析構順序

標籤：c++

#include<iostream>#include<string.h>using namespace std;class String_date{private:    char * str;public:    String_date(char * str);    ~String_date();    char* get_infor()    {return str;}};String_date::String_date(char* s){    cout<<"constructing:"<<endl;    str = new char [strlen(s) + 1];    strcpy(str,s);}String_date::~String_date(){    delete str;    cout<<"destructing:"<<str<<endl;//只要在解構函式中加入有效列印語句就可以辨別}int main(){    String_date str1("teacher");    String_date str2("student");    cout<<str1.get_infor()<<endl;    return 0;}
