设计一个Person类，其属性包括姓名name和身份证号 id，其中name为字符串类型，id 为整型，编写成员函数：构造函数Person、Display函数（显示数据成员信息)和析构函数，再由Person类派生出大学生类CollegeStu，其属性有专业maior（字符串类型)，C++程设计课程成绩score（ double型),编写构造函数(实现数据初始化 )、输出函数Display（包括 name, id , major , score ).

以下是Person类和CollegeStu类的实现代码：

#include <iostream>
#include <string>
using namespace std;

class Person {
protected:
    string name;
    int id;
public:
    Person(string n, int i) {
        name = n;
        id = i;
        cout << "Constructing Person: " << name << endl;
    }
    ~Person() {
        cout << "Destructing Person: " << name << endl;
    }
    void Display() {
        cout << "Name: " << name << endl;
        cout << "ID: " << id << endl;
    }
};

class CollegeStu : public Person {
private:
    string major;
    double score;
public:
    CollegeStu(string n, int i, string m, double s) : Person(n, i) {
        major = m;
        score = s;
        cout << "Constructing CollegeStu: " << name << endl;
    }
    ~CollegeStu() {
        cout << "Destructing CollegeStu: " << name << endl;
    }
    void Display() {
        cout << "Name: " << name << endl;
        cout << "ID: " << id << endl;
        cout << "Major: " << major << endl;
        cout << "Score: " << score << endl;
    }
};

int main() {
    CollegeStu stu("Tom", 123456, "Computer Science", 90.5);
    stu.Display();
    return 0;
}

输出结果如下：

Constructing Person: Tom
Constructing CollegeStu: Tom
Name: Tom
ID: 123456
Major: Computer Science
Score: 90.5
Destructing CollegeStu: Tom
Destructing Person: Tom

在该实现中，Person类作为CollegeStu类的基类，CollegeStu类继承了Person类的属性和成员函数，并新增了专业和成绩两个属性。在CollegeStu类的构造函数中，首先调用了Person类的构造函数来初始化name和id属性，然后再初始化新增的major和score属性。在CollegeStu类的Display函数中，除了输出继承自Person类的name和id属性之外，还输出了新增的major和score属性。在程序结束时，先调用CollegeStu类的析构函数，再调用Person类的析构函数。
