基于c++语言设计设计职工信息表,并由此产生一个信息简表,并使用虚函数实现多态性,完成显示不同简表信息的任务。使用了继承的方法,编写最多能输入10个职工的信息表,再根据这个表产生一个职工信息简表,并利用多

态性实现不同类型的职工信息简表。

下面是一个简单的示例代码：

#include <iostream>
#include <string>

using namespace std;

class Employee {
protected:
    string name;
    int age;
    string gender;
    double salary;
public:
    Employee(string n, int a, string g, double s) {
        name = n;
        age = a;
        gender = g;
        salary = s;
    }
    virtual void display() {}
};

class Manager : public Employee {
private:
    string department;
public:
    Manager(string n, int a, string g, double s, string d) : Employee(n, a, g, s) {
        department = d;
    }
    void display() {
        cout << "Name: " << name << endl;
        cout << "Age: " << age << endl;
        cout << "Gender: " << gender << endl;
        cout << "Salary: " << salary << endl;
        cout << "Department: " << department << endl;
    }
};

class Engineer : public Employee {
private:
    string project;
public:
    Engineer(string n, int a, string g, double s, string p) : Employee(n, a, g, s) {
        project = p;
    }
    void display() {
        cout << "Name: " << name << endl;
        cout << "Age: " << age << endl;
        cout << "Gender: " << gender << endl;
        cout << "Salary: " << salary << endl;
        cout << "Project: " << project << endl;
    }
};

int main() {
    Employee *employees[10];

    // 加入几个经理和工程师
    employees[0] = new Manager("John", 45, "Male", 80000, "Sales");
    employees[1] = new Engineer("Mary", 30, "Female", 60000, "Software");
    employees[2] = new Manager("Tom", 50, "Male", 90000, "Marketing");
    employees[3] = new Engineer("Susan", 35, "Female", 65000, "Hardware");

    // 显示职工信息
    for (int i = 0; i < 4; i++) {
        employees[i]->display();
        cout << endl;
    }

    return 0;
}

在这个例子中，我们定义了一个 `Employee` 类作为基类，然后派生出了 `Manager` 和 `Engineer` 两个子类。每个子类都重写了 `display()` 函数，以显示不同的信息。在主函数中，我们创建了一个由 `Employee` 的指针组成的数组，并加入了几个经理和工程师的信息。然后，我们循环遍历这个数组，并调用每个指针指向的对象的 `display()` 函数，以显示不同类型的职工信息简表。
