写c++程序 设计一个通讯录系统，联系人基本信息包括：联系人姓名、手机号码、邮箱、工作单位、家庭住址等基本信息，完成下面的功能需求，根据功能需求选择合适的逻辑结构和存储结构。二、功能需求（1）增加功能：能添加新的联系人信息。（2）删除功能：能够删除通讯录中的联系人。（3）修改功能：能够对通讯录中的联系人信息进行修改。（4）查询功能：通过员工号查询员工信息，并显示该员工所有信息。（5）排序功能：可以对联系人信息排序，对联系人姓名按照字典序排序，之后显示排序后的通讯录所有联系人信息。（6）显示功能：显示通讯录中所有联系人信息。功能：能够从文本中读取联系人信息，对联系人信息更改之后可以将通讯录中联系人信息保存到文本中，方便下次读取。

好，这是一个比较详细的功能需求，我可以为你提供一个基本的 C++ 程序框架，你可以在此基础上进行修改和完善，实现你所需要的功能。程序主要分为以下几个部分：

1. 定义联系人结构体

struct Contact {
    std::string name;
    std::string phone;
    std::string email;
    std::string company;
    std::string address;
};

2. 定义通讯录类

class AddressBook {
public:
    // 添加联系人
    void addContact(const Contact& contact);
    
    // 删除联系人
    void deleteContact(const std::string& name);
    
    // 修改联系人信息
    void modifyContact(const std::string& name, const Contact& contact);
    
    // 查询联系人信息
    void queryContact(const std::string& name);
    
    // 排序联系人信息
    void sortContacts();
    
    // 显示所有联系人信息
    void displayAllContacts();
    
    // 从文件中读取联系人信息
    void readContactsFromFile(const std::string& filename);
    
    // 将联系人信息保存到文件中
    void saveContactsToFile(const std::string& filename);
private:
    std::vector<Contact> contacts_;
};

3. 实现通讯录类的各个方法

void AddressBook::addContact(const Contact& contact) {
    contacts_.push_back(contact);
}

void AddressBook::deleteContact(const std::string& name) {
    for (auto it = contacts_.begin(); it != contacts_.end(); ++it) {
        if (it->name == name) {
            contacts_.erase(it);
            break;
        }
    }
}

void AddressBook::modifyContact(const std::string& name, const Contact& contact) {
    for (auto& c : contacts_) {
        if (c.name == name) {
            c.phone = contact.phone;
            c.email = contact.email;
            c.company = contact.company;
            c.address = contact.address;
            break;
        }
    }
}

void AddressBook::queryContact(const std::string& name) {
    for (const auto& c : contacts_) {
        if (c.name == name) {
            std::cout << "Name: " << c.name << std::endl;
            std::cout << "Phone: " << c.phone << std::endl;
            std::cout << "Email: " << c.email << std::endl;
            std::cout << "Company: " << c.company << std::endl;
            std::cout << "Address: " << c.address << std::endl;
            return;
        }
    }
    std::cout << "Contact not found." << std::endl;
}

void AddressBook::sortContacts() {
    std::sort(contacts_.begin(), contacts_.end(), [](const Contact& c1, const Contact& c2) {
        return c1.name < c2.name;
    });
}

void AddressBook::displayAllContacts() {
    for (const auto& c : contacts_) {
        std::cout << "Name: " << c.name << std::endl;
        std::cout << "Phone: " << c.phone << std::endl;
        std::cout << "Email: " << c.email << std::endl;
        std::cout << "Company: " << c.company << std::endl;
        std::cout << "Address: " << c.address << std::endl;
        std::cout << std::endl;
    }
}

void AddressBook::readContactsFromFile(const std::string& filename) {
    std::ifstream file(filename);
    if (!file.is_open()) {
        std::cerr << "Failed to open file: " << filename << std::endl;
        return;
    }
    std::string line;
    while (std::getline(file, line)) {
        std::vector<std::string> fields;
        std::istringstream iss(line);
        std::string field;
        while (std::getline(iss, field, ',')) {
            fields.push_back(field);
        }
        if (fields.size() != 5) {
            std::cerr << "Invalid file format." << std::endl;
            return;
        }
        Contact contact;
        contact.name = fields[0];
        contact.phone = fields[1];
        contact.email = fields[2];
        contact.company = fields[3];
        contact.address = fields[4];
        addContact(contact);
    }
}

void AddressBook::saveContactsToFile(const std::string& filename) {
    std::ofstream file(filename);
    if (!file.is_open()) {
        std::cerr << "Failed to open file: " << filename << std::endl;
        return;
    }
    for (const auto& c : contacts_) {
        file << c.name << "," << c.phone << "," << c.email << "," << c.company << "," << c.address << std::endl;
    }
}

4. 在主函数中使用通讯录类

int main() {
    AddressBook addressBook;
    addressBook.readContactsFromFile("contacts.txt");

    while (true) {
        int choice;
        std::cout << "1. Add contact" << std::endl;
        std::cout << "2. Delete contact" << std::endl;
        std::cout << "3. Modify contact" << std::endl;
        std::cout << "4. Query contact" << std::endl;
        std::cout << "5. Sort contacts" << std::endl;
        std::cout << "6. Display all contacts" << std::endl;
        std::cout << "7. Save contacts to file" << std::endl;
        std::cout << "8. Exit" << std::endl;
        std::cout << "Enter your choice: ";
        std::cin >> choice;

        switch (choice) {
        case 1: {
            Contact contact;
            std::cout << "Enter name: ";
            std::cin >> contact.name;
            std::cout << "Enter phone: ";
            std::cin >> contact.phone;
            std::cout << "Enter email: ";
            std::cin >> contact.email;
            std::cout << "Enter company: ";
            std::cin >> contact.company;
            std::cout << "Enter address: ";
            std::cin >> contact.address;
            addressBook.addContact(contact);
            std::cout << "Contact added." << std::endl;
            break;
        }
        case 2: {
            std::string name;
            std::cout << "Enter name: ";
            std::cin >> name;
            addressBook.deleteContact(name);
            std::cout << "Contact deleted." << std::endl;
            break;
        }
        case 3: {
            std::string name;
            Contact contact;
            std::cout << "Enter name: ";
            std::cin >> name;
            std::cout << "Enter phone: ";
            std::cin >> contact.phone;
            std::cout << "Enter email: ";
            std::cin >> contact.email;
            std::cout << "Enter company: ";
            std::cin >> contact.company;
            std::cout << "Enter address: ";
            std::cin >> contact.address;
            addressBook.modifyContact(name, contact);
            std::cout << "Contact modified." << std::endl;
            break;
        }
        case 4: {
            std::string name;
            std::cout << "Enter name: ";
            std::cin >> name;
            addressBook.queryContact(name);
            break;
        }
        case 5: {
            addressBook.sortContacts();
            std::cout << "Contacts sorted." << std::endl;
            break;
        }
        case 6: {
            addressBook.displayAllContacts();
            break;
        }
        case 7: {
            addressBook.saveContactsToFile("contacts.txt");
            std::cout << "Contacts saved to file." << std::endl;
            break;
        }
        case 8: {
            return 0;
        }
        default: {
            std::cout << "Invalid choice." << std::endl;
            break;
        }
        }
    }

    return 0;
}

这个程序框架可以实现你所需的基本功能，你可以根据需求进行修改和完善。
