用C++写一个mytel和telmanager类，后者有mytel的子对象，实现查找，增添，删除，修改

好的，下面是一个实现增删改查的MyTel和TelManager类的C++代码：

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

using namespace std;

class MyTel {
public:
    MyTel(string name, string number) : name_(name), number_(number) {}
    string getName() const { return name_; }
    string getNumber() const { return number_; }
    void setName(string name) { name_ = name; }
    void setNumber(string number) { number_ = number; }
private:
    string name_;
    string number_;
};

class TelManager {
public:
    void addMyTel(MyTel mytel) { mytels_.push_back(mytel); }
    void printAllMyTels() const {
        for (const auto& mytel : mytels_) {
            cout << "Name: " << mytel.getName() << ", Number: " << mytel.getNumber() << endl;
        }
    }
    MyTel* findMyTel(string name) {
        for (auto& mytel : mytels_) {
            if (mytel.getName() == name) {
                return &mytel;
            }
        }
        return nullptr;
    }
    void deleteMyTel(string name) {
        for (auto it = mytels_.begin(); it != mytels_.end(); ++it) {
            if (it->getName() == name) {
                mytels_.erase(it);
                break;
            }
        }
    }
    void modifyMyTel(string name, string new_name, string new_number) {
        for (auto& mytel : mytels_) {
            if (mytel.getName() == name) {
                mytel.setName(new_name);
                mytel.setNumber(new_number);
                break;
            }
        }
    }
private:
    vector<MyTel> mytels_;
};

int main() {
    MyTel mytel1("Alice", "1234567");
    MyTel mytel2("Bob", "2345678");

    TelManager telmanager;
    telmanager.addMyTel(mytel1);
    telmanager.addMyTel(mytel2);

    // 查找
    cout << "Find \"Alice\"" << endl;
    MyTel* mytel = telmanager.findMyTel("Alice");
    if (mytel) {
        cout << "Found: Name: " << mytel->getName() << ", Number: " << mytel->getNumber() << endl;
    } else {
        cout << "Not found" << endl;
    }

    // 增加
    cout << endl << "Add \"Carl\", \"3456789\"" << endl;
    telmanager.addMyTel(MyTel("Carl", "3456789"));
    telmanager.printAllMyTels();

    // 删除
    cout << endl << "Delete \"Alice\"" << endl;
    telmanager.deleteMyTel("Alice");
    telmanager.printAllMyTels();

    // 修改
    cout << endl << "Modify \"Bob\"" << endl;
    telmanager.modifyMyTel("Bob", "Bobby", "4567890");
    telmanager.printAllMyTels();

    return 0;
}

这里我们在MyTel类中添加了setName和setNumber方法，用于修改MyTel对象的名字和电话号码。在TelManager类中，我们添加了findMyTel、deleteMyTel和modifyMyTel方法，用于查找、删除和修改MyTel对象。在main函数中，我们演示了如何使用这些方法来增删改查MyTel对象。
