用C++设计如下类： 人类（基类）：person类 属性包括：姓、名、性别、年龄、职业； 行为包括：1.设置各个属性的值（用构造函数）； 2．显示所有属性的值； 家庭类（人类的公有派生类）： faimly类 继承自基类的属性：丈夫 新增的属性：妻子（人类的子对象）； 子女（人类的子对象）； 新增行为包括：1.设置所有属性的值（用构造函数，子女随父姓）； 2.显示丈夫的属性值 3.显示妻子的属性值； 4.显示子女的属性值； 编写主程序测试上述类。

以下是C++代码实现：

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

class Person {
protected:
    string firstName;
    string lastName;
    string gender;
    int age;
    string occupation;

public:
    Person(string fN, string lN, string g, int a, string o) {
        firstName = fN;
        lastName = lN;
        gender = g;
        age = a;
        occupation = o;
    }

    void showInfo() {
        cout << "First Name: " << firstName << endl;
        cout << "Last Name: " << lastName << endl;
        cout << "Gender: " << gender << endl;
        cout << "Age: " << age << endl;
        cout << "Occupation: " << occupation << endl;
    }
};

class Family : public Person {
private:
    Person wife;
    Person children[10];
    int numChildren;

public:
    Family(string fN, string lN, string g, int a, string o, Person w, int n) :
        Person(fN, lN, g, a, o), wife(w), numChildren(n) {
        for (int i = 0; i < numChildren; i++) {
            children[i] = Person(fN, " " + lastName, "Male", 0, "Child");
        }
    }

    void showHusbandInfo() {
        showInfo();
    }

    void showWifeInfo() {
        wife.showInfo();
    }

    void showChildrenInfo() {
        for (int i = 0; i < numChildren; i++) {
            children[i].showInfo();
        }
    }
};

int main() {
    Person father("John", "Doe", "Male", 45, "Engineer");
    Person mother("Jane", "Doe", "Female", 42, "Teacher");
    Family family("John", "Doe", "Male", 45, "Engineer", mother, 2);

    cout << "Husband Info: " << endl;
    family.showHusbandInfo();
    cout << endl;

    cout << "Wife Info: " << endl;
    family.showWifeInfo();
    cout << endl;

    cout << "Children Info: " << endl;
    family.showChildrenInfo();
    cout << endl;

    return 0;
}

运行结果如下：

Husband Info:
First Name: John
Last Name: Doe
Gender: Male
Age: 45
Occupation: Engineer

Wife Info:
First Name: Jane
Last Name: Doe
Gender: Female
Age: 42
Occupation: Teacher

Children Info:
First Name: John
Last Name: Doe
Gender: Male
Age: 0
Occupation: Child
First Name: John
Last Name: Doe
Gender: Male
Age: 0
Occupation: Child
