以下是修改后的代码：

#include<iostream> 
#include<vector> // 添加头文件vector
using namespace std; 

class Person {
public:
    Person(string name, string phone, string email)
        : name_(name), phone_(phone), email_(email) {}
    string GetName() const { return name_; }
    string GetPhone() const { return phone_; }
    string GetEmail() const { return email_; }
    void SetPhone(string phone) { phone_ = phone; }
    void SetEmail(string email) { email_ = email; }
private:
    string name_;
    string phone_;
    string email_;
};

class AddressBook {
public:
    AddressBook() {}
    void AddPerson(const Person& person) {
        persons_.push_back(person); // 修改变量名person为persons_
    }
    void RemovePerson(const string& name) {
        for (auto it = persons_.begin(); it != persons_.end(); ++it) {
            if (it->GetName() == name) {
                persons_.erase(it);
                break;
            }
        }
    }
    Person FindPerson(const string& name) const {
        for (auto& person : persons_) { // 修改变量名Person为persons_
            if (person.GetName() == name) {
                return person;
            }
        }
        return Person("", "", "");
    }
private:
    vector<Person> persons_; // 修改变量类型char <Person>为vector<Person>
};

int main() {
    AddressBook address_book;

    // 添加联系人
    address_book.AddPerson(Person("张三", "13312345678", "zhangsan@qq.com"));
    address_book.AddPerson(Person("李四", "13987654321", "lisi@qq.com"));

    // 删除联系人
    address_book.RemovePerson("李四");

    // 查找联系人
    Person person = address_book.FindPerson("张三");
    if (person.GetName() != "") {
        cout << "姓名：" << person.GetName() << endl;
        cout << "电话：" << person.GetPhone() << endl;
        cout << "邮箱：" << person.GetEmail() << endl;
    } else {
        cout << "未找到该联系人！" << endl;
    }

    return 0;
}

主要修改：

- 添加头文件vector。
- 修改变量名person为persons_，并修改类型为vector<Person>。
- 修改遍历persons_时的变量名Person为person。
