1. 题目描述
   对people类重载“= =”运算符和“＝”运算符，“＝＝”运算符判断两个people类对象的id属性是否相等；“=”运算符实现people类对象的赋值操作。
2. 代码如下

#include
     
      #include
      
       using namespace std;class Data{public:    Data(){}    Data(int yy,int mm,int dd){    year=yy;    month=mm;    day=dd;    }    Data(Data &ap){        year=ap.year;        month=ap.month;        day=ap.day;    }    ~Data(){    }    int get_year(){        return year;    }    int get_month(){        return month;    }    int get_day(){        return day;    }    void set_year(int y){        year=y;    }    void set_month(int m){        month=m;    }    void set_day(int d){        day=d;    }private:    int year;    int month;    int day;};class People{public:    People(int num,string se,Data birth,string iid):birthday(birth){        number=num;        sex=se;        id=iid;    }    People(People &tp){        number=tp.get_number();        sex=tp.get_sex();        id=tp.get_id();        birthday=tp.get_birthday();    }    People(){}    People get_People(){        int num,yy,mm,dd;        string ID,se;        cout<<"Please enter the number of the People:"<
       
        >num;        cout<<"Please enter the sex:(male or female)"<
        
         >se;        cout<<"Please enter the birthday:"            <<"(Warning the format is 1998 8 3.)"<
         
          >yy>>mm>>dd;        cout<<"Please enter the id:"<
          
           >ID; Data birth(yy,mm,dd); id=ID; number=num; sex=se; birthday=birth; return *this; } ~People(){} void set_number(int num){ number=num; } void set_sex(string se){ sex=se; } void set_birhtday(Data birth){ birthday=birth; } void set_id(string iidd){ id=iidd; } inline int get_number(){ return number; } inline string get_sex(){ return sex; } Data get_birthday() { return birthday; } inline string get_id(){ return id; } void details(){ cout<<"Number:"<
           
            <
