用c++代码写一个家谱管理系统

这里给出一个简单的家谱管理系统的C++代码，基于面向对象的思想，包含了家庭成员的基本信息、家庭成员之间的关系以及一些简单的操作函数。

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

class Person {
public:
    string name;
    string gender;
    int age;
    vector<Person*> children;
    Person(string n, string g, int a) :name(n), gender(g), age(a) {}
};

class FamilyTree {
private:
    Person* root;
public:
    FamilyTree(Person* r) :root(r) {}
    void addChild(Person* parent, Person* child);
    void deleteChild(Person* parent, Person* child);
    void showFamilyTree(Person* root);
};

void FamilyTree::addChild(Person* parent, Person* child) {
    parent->children.push_back(child);
}

void FamilyTree::deleteChild(Person* parent, Person* child) {
    vector<Person*>::iterator it = parent->children.begin();
    while (it != parent->children.end()) {
        if (*it == child) {
            parent->children.erase(it);
            break;
        }
        it++;
    }
}

void FamilyTree::showFamilyTree(Person* root) {
    cout << "Name: " << root->name << ", Gender: " << root->gender << ", Age: " << root->age << endl;
    if (root->children.empty()) return;
    for (auto child : root->children) {
        showFamilyTree(child);
    }
}

int main() {
    // 初始化家庭成员
    Person* grandpa = new Person("Grandpa", "Male", 70);
    Person* grandma = new Person("Grandma", "Female", 68);
    Person* father = new Person("Father", "Male", 45);
    Person* mother = new Person("Mother", "Female", 40);
    Person* son1 = new Person("Son1", "Male", 20);
    Person* son2 = new Person("Son2", "Male", 18);
    Person* daughter = new Person("Daughter", "Female", 16);

    // 初始化家谱
    FamilyTree familyTree(grandpa);
    familyTree.addChild(grandpa, grandma);
    familyTree.addChild(grandpa, father);
    familyTree.addChild(father, mother);
    familyTree.addChild(father, son1);
    familyTree.addChild(father, son2);
    familyTree.addChild(father, daughter);

    // 显示家谱
    familyTree.showFamilyTree(grandpa);

    // 删除一个孩子后再次显示家谱
    familyTree.deleteChild(father, son2);
    cout << "After deleting Son2: " << endl;
    familyTree.showFamilyTree(grandpa);

    return 0;
}

这个家谱管理系统定义了 `Person` 和 `FamilyTree` 两个类，其中 `Person` 类表示每个家庭成员，包含姓名 `name`、性别 `gender`、年龄 `age` 和子女 `children`。 `FamilyTree` 类表示整个家谱，包含根节点 `root` 和添加子女、删除子女、显示家谱的三个操作函数。在 `main` 中初始化了一些家庭成员和家谱，并通过 `familyTree.showFamilyTree(grandpa)` 显示了整个家谱。
