C++定义个人信息类Person，其数据成员有姓名、性别、出生年月。并以Person为基类定义一个学生的派生类Student，增加描述学生的信息：班级、学号、专业、英语成绩和数学成绩。再由基类Person定义一个职工的派生类Employee，增加描述职工的信息：部门、职 务、工资。编程实现学生与职工信息的输入与输出

：好的，我能够理解您的问题。以下是对应的代码实现：

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

class Person{
protected:
    string name;
    char sex;
    int birthYear, birthMonth;
public:
    Person(string name, char sex, int birthYear, int birthMonth){
        this->name = name;
        this->sex = sex;
        this->birthYear = birthYear;
        this->birthMonth = birthMonth;
    }
    void display(){
        cout << "姓名：" << name << endl;
        cout << "性别：" << sex << endl;
        cout << "出生日期：" << birthYear << "年" << birthMonth << "月" << endl;
    }
};

class Student : public Person{
protected:
    string className;
    string studentID;
    string major;
    double englishGrade;
    double mathGrade;
public:
    Student(string className, string studentID, string major, double englishGrade, double mathGrade, string name, char sex, int birthYear, int birthMonth): Person(name, sex, birthYear, birthMonth){
        this->className = className;
        this->studentID = studentID;
        this->major = major;
        this->englishGrade = englishGrade;
        this->mathGrade = mathGrade;
    }
    void display(){
        Person::display();
        cout << "班级：" << className << endl;
        cout << "学号：" << studentID << endl;
        cout << "专业：" << major << endl;
        cout << "英语成绩：" << englishGrade << endl;
        cout << "数学成绩：" << mathGrade << endl;
    }
};

class Employee : public Person{
protected:
    string department;
    string position;
    double salary;
public:
    Employee(string department, string position, double salary, string name, char sex, int birthYear, int birthMonth): Person(name, sex, birthYear, birthMonth){
        this->department = department;
        this->position = position;
        this->salary = salary;
    }
    void display(){
        Person::display();
        cout << "部门：" << department << endl;
        cout << "职务：" << position << endl;
        cout << "工资：" << salary << endl;
    }
};

int main(){
    string name;
    char sex;
    int birthYear, birthMonth;
    string className, studentID, major;
    double englishGrade, mathGrade;
    string department, position;
    double salary;

    cout << "请输入学生信息：" << endl;
    cout << "姓名：";
    cin >> name;
    cout << "性别：";
    cin >> sex;
    cout << "出生年份：";
    cin >> birthYear;
    cout << "出生月份：";
    cin >> birthMonth;
    cout << "班级：";
    cin >> className;
    cout << "学号：";
    cin >> studentID;
    cout << "专业：";
    cin >> major;
    cout << "英语成绩：";
    cin >> englishGrade;
    cout << "数学成绩：";
    cin >> mathGrade;

    Student stu(className, studentID, major, englishGrade, mathGrade, name, sex, birthYear, birthMonth);
    cout << endl << "学生信息如下：" << endl;
    stu.display();

    cout << endl << "请输入职工信息：" << endl;
    cout << "姓名：";
    cin >> name;
    cout << "性别：";
    cin >> sex;
    cout << "出生年份：";
    cin >> birthYear;
    cout << "出生月份：";
    cin >> birthMonth;
    cout << "部门：";
    cin >> department;
    cout << "职务：";
    cin >> position;
    cout << "工资：";
    cin >> salary;

    Employee emp(department, position, salary, name, sex, birthYear, birthMonth);
    cout << endl << "职工信息如下：" << endl;
    emp.display();

    return 0;
}

希望上述代码能够满足您的需求。
