下面是一个特别简单的例子,但我觉得挺有趣的,并且有助于对构造函数与析构函数的调用时机的了解。

修改下面给出的程序,但不允许对main()函数作任何修改,使程序能够在屏幕上输出:
The most distant way in the world
is not the way from birth to the end
It is when I sit near you
that you don't understand I love you
原来的程序为:
int main() { cout<<"It is when I sit near you"< #includeusing namespace std; class Poetry { public: Poetry() { cout<<"The most distant way in the worldn"; cout<<"is not the way from birth to the endn"; } ~Poetry() { cout<<"that you don't understand I love you.n"; } }; int main() { //定义一个对象 Poetry p; cout<<"It is when I sit near you"< 观察程序,可以通过输出感受(不解释啦~~)
