在派生类Teacher_Cadre的成员函数show中调用Teacher类中的display函数，输出姓名、年龄、性别、职称、地址、电话、然后再用cout语句输出职务与工资。

假设Teacher类和Teacher_Cadre类的定义如下：

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

class Teacher {
protected:
    string name;
    int age;
    char gender;
    string title;
    string address;
    string phone;

public:
    Teacher(string name, int age, char gender, string title, string address, string phone) {
        this->name = name;
        this->age = age;
        this->gender = gender;
        this->title = title;
        this->address = address;
        this->phone = phone;
    }

    void display() {
        cout << "姓名：" << name << endl;
        cout << "年龄：" << age << endl;
        cout << "性别：" << gender << endl;
        cout << "职称：" << title << endl;
        cout << "地址：" << address << endl;
        cout << "电话：" << phone << endl;
    }
};

class Teacher_Cadre : public Teacher {
private:
    string duty;
    float salary;

public:
    Teacher_Cadre(string name, int age, char gender, string title, string address, string phone, string duty, float salary)
        : Teacher(name, age, gender, title, address, phone) {
        this->duty = duty;
        this->salary = salary;
    }

    void show() {
        display();
        cout << "职务：" << duty << endl;
        cout << "工资：" << salary << endl;
    }
};

在Teacher_Cadre类的show函数中，可以直接调用Teacher类的display函数来输出姓名、年龄、性别、职称、地址、电话：

void Teacher_Cadre::show() {
    display();
    cout << "职务：" << duty << endl;
    cout << "工资：" << salary << endl;
}

其中，display函数是Teacher类中的成员函数，可以直接在Teacher_Cadre类的成员函数中调用。
