用c++写一个家谱管理系统

下面是一个简单的家谱管理系统的 C++ 代码示例：

#include <iostream>
#include <string>
#include <vector>

using namespace std;

class Person {
public:
    Person(string name, string gender, int age) {
        this->name = name;
        this->gender = gender;
        this->age = age;
    }

    string getName() {
        return name;
    }

    string getGender() {
        return gender;
    }

    int getAge() {
        return age;
    }

    void display() {
        cout << "Name: " << name << endl;
        cout << "Gender: " << gender << endl;
        cout << "Age: " << age << endl;
    }

private:
    string name;
    string gender;
    int age;
};

class FamilyTree {
public:
    FamilyTree(string rootName, string rootGender, int rootAge) {
        root = new Person(rootName, rootGender, rootAge);
    }

    ~FamilyTree() {
        delete root;
    }

    void addChild(string parentName, string childName, string gender, int age) {
        Person *parent = findPerson(parentName);
        if (parent == nullptr) {
            cout << parentName << " is not found in the family tree." << endl;
            return;
        }

        parent->display();
        cout << "has a child named " << childName << endl;
        Person *child = new Person(childName, gender, age);
        children.push_back(child);
    }

    void display() {
        cout << "Family Tree:" << endl;
        root->display();
        for (int i = 0; i < children.size(); i++) {
            children[i]->display();
        }
    }

private:
    Person *root;
    vector<Person *> children;

    Person *findPerson(string name) {
        if (root->getName() == name) {
            return root;
        }

        for (int i = 0; i < children.size(); i++) {
            if (children[i]->getName() == name) {
                return children[i];
            }
        }

        return nullptr;
    }
};

int main() {
    FamilyTree *familyTree = new FamilyTree("Jack", "Male", 50);
    familyTree->addChild("Jack", "Tom", "Male", 25);
    familyTree->addChild("Jack", "Lily", "Female", 22);
    familyTree->addChild("Tom", "Jerry", "Male", 2);
    familyTree->display();
    delete familyTree;
    return 0;
}

这个程序实现了一个简单的家谱管理系统，包含了两个类：`Person` 和 `FamilyTree`。

`Person` 类包含了一个人的基本信息，包括姓名、性别和年龄。

`FamilyTree` 类实现了家谱管理系统的功能，包括添加子女和显示家谱等。

在 `main` 函数中，我们创建一个 `FamilyTree` 对象，并添加一些人物信息，最后调用 `display` 方法显示整个家谱。
