xiaoping刚接触类的构造和析构函数，对于构造函数的编写比较困惑。zhuangzhuang给小平布置了一道题目，xiaoping苦思两天也无法解答，请你帮帮xiaoping吧。

#include <iostream>
using namespace std;
class XiaoPing
{
private:
    int state;   //用来记录是否有参数
    int data;
public:

XiaoPing();
    XiaoPing(int data);
    ~XiaoPing();
};
//

只需完成并提交该部分代码

///
XiaoPing::~XiaoPing()
{
    if(state)
        cout<<"destroy an object with a parameter:"<<data<<endl;
    else
        cout<<"destroy an object with no parameter"<<endl;
}
int main()
{
    int data;
    XiaoPing zeropara1;
    cin>>data;
    XiaoPing onepara1(data);
    XiaoPing zeropara2;
    cin>>data;
    XiaoPing onepara2(data);
    return 0;
}

输入两行。每行一个整数，表示构造函数的参数值。

按照题意输出构造函数和析构函数的调用顺序和信息。

#include <iostream>
using namespace std;
class XiaoPing
{
private:int state;int data;
public:XiaoPing();XiaoPing(int data);~XiaoPing();
};
XiaoPing::XiaoPing()
{state=0;
}
XiaoPing::XiaoPing(int dat)
{state=1;data=dat;cout<<"create an object with no parameter"<<endl;cout<<"create an object with a parameter:"<<data<<endl;
}
XiaoPing::~XiaoPing()
{if(state)cout<<"destory an object with a parameter:"<<data<<endl;elsecout<<"destory an object with no parameter"<<endl;
}
int main()
{int data;XiaoPing zeropara1;cin>>data;XiaoPing onepara1(data);XiaoPing zeropara2;cin>>data;XiaoPing onepara2(data);return 0;
}
