类单元实验？（不成功）

//构造一个People类来进行人员管理，要求用上内联，构造，析构，类的组合
#include<iostream>
#include<string>
using namespace std;
class Date{                    //定义一个存储出生日期的类
	int year,mouth,day;
	public :
		Date(int y,int m,int d);//构造函数
		Date();//默认构造函数
		Date(const Date&);//复制构造函数
		~Date();//析构函数
		void inputData();//输入数据
		void showData();//显示数据
};
Date::Date(int y,int m,int d):year(y),mouth(m),day(d){
	cout<<"构造了一个Date对象。。。"<<endl;

int main()
{
	Date b1;
	People people1("name","id",b1,0,'m');
	people1.inputData();
	people1.showData();
        people1.~People;
	return 0;
}

构造的和析构的不对等.....找不出来问题....有点烦，标记着，学完后面回来 看看.....
people析构多出来一个是我自己调用了一次.......去掉后正常了...
感谢老师指导，给复制构造函数的输出区别于构造函数，现在清楚了
