编写一个创建时,就在屏幕上打印Hello,消失时,就打印Goodbye 的C++程序.

#include<iostream>
using namespace std;

class World{
        public:
                World(){//创建时
                        std::cout<<"Hello!\n";
                }
                ~World(){//消失时
                        std::cout<<"Goodbye!\n";
                }
};

//World theWorld;

int main(){
        //cout<<"Hello World\n";
        World theWorld;
        return 0;
}

[root@portal ctest]# vi hello.c
[root@portal ctest]# g++ hello.c -o hello
[root@portal ctest]# ./hello
Hello!
Goodbye!
[root@portal ctest]#
