理解您的困扰，作为一位经验丰富的程序员，我会帮你逐步解决这个问题。首先，我们可以将这个项目分解成几个小的部分，并逐一实现这些功能。这里是一个简单的C++类设计和部分功能的实现，你可以根据这个模板继续完善你的程序。

#include <iostream>
#include <vector>
#include <algorithm>
#include <string>
#include <map>
#include <iomanip>

class Worker {
public:
    int id;
    std::string name;
    std::string department;
    std::string title;
    double basic_salary;
    double overtime_salary;
    double bonus;
    double total_salary;

    Worker(int id, const std::string& name, const std::string& department,
           const std::string& title, double basic_salary, double overtime_salary,
           double bonus)
        : id(id), name(name), department(department), title(title),
          basic_salary(basic_salary), overtime_salary(overtime_salary),
          bonus(bonus), total_salary(basic_salary + overtime_salary + bonus) {}
};

bool compareByTotalSalary(const Worker& a, const Worker& b) {
    return a.total_salary > b.total_salary;
}

bool compareByBasicSalary(const Worker& a, const Worker& b) {
    return a.basic_salary > b.basic_salary;
}

class WorkerDatabase {
private:
    std::vector<Worker> workers;
    std::map<std::string, int> titleCount;

public:
    void addWorker(const Worker& worker) {
        workers.push_back(worker);
        incrementTitleCount(worker.title);
    }

    Worker findWorkerById(int id) const {
        for (const auto& worker : workers) {
            if (worker.id == id) {
                return worker;
            }
        }
        throw std::runtime_error("Worker not found");
    }

    Worker findWorkerByName(const std::string& name) const {
        for (const auto& worker : workers) {
            if (worker.name == name) {
                return worker;
            }
        }
        throw std::runtime_error("Worker not found");
    }

    void sortWorkersByTotalSalary() {
        std::sort(workers.begin(), workers.end(), compareByTotalSalary);
    }

    void sortWorkersByBasicSalary() {
        std::sort(workers.begin(), workers.end(), compareByBasicSalary);
    }

    void deleteWorkerById(int id) {
        workers.erase(std::remove_if(workers.begin(), workers.end(),
                                     [id](const Worker& worker) { return worker.id == id; }),
                      workers.end());
    }

    void modifyWorkerById(int id, const Worker& updatedWorker) {
        for (auto& worker : workers) {
            if (worker.id == id) {
                worker = updatedWorker;
                break;
            }
        }
    }

    double calculateAverageSalary(const std::string& department) const {
        double sum = 0;
        int count = 0;
        for (const auto& worker : workers) {
            if (worker.department == department) {
                sum += worker.total_salary;
                count++;
            }
        }
        return count > 0 ? sum / count : 0;
    }

    double calculatePercentageOfTitle(const std::string& title) const {
        return static_cast<double>(titleCount[title]) / workers.size();
    }

    void displayWorkerTable() const {
        std::cout << std::setw(10) << "ID" << std::setw(15) << "Name"
                  << std::setw(15) << "Department" << std::setw(15) << "Title"
                  << std::setw(15) << "Basic Salary" << std::setw(15) << "Overtime Salary"
                  << std::setw(15) << "Bonus" << std::setw(15) << "Total Salary\n";
        for (const auto& worker : workers) {
            std::cout << std::setw(10) << worker.id << std::setw(15) << worker.name
                      << std::setw(15) << worker.department << std::setw(15) << worker.title
                      << std::setw(15) << worker.basic_salary << std::setw(15)
                      << worker.overtime_salary << std::setw(15) << worker.bonus
                      << std::setw(15) << worker.total_salary << '\n';
        }
    }

private:
    void incrementTitleCount(const std::string& title) {
        titleCount[title]++;
    }
};

int main() {
    WorkerDatabase db;
    // 添加职工记录
    db.addWorker(Worker(1, "Alice", "IT", "Engineer", 5000, 1000, 500));
    db.addWorker(Worker(2, "Bob", "HR", "Manager", 8000, 1500, 1000));

    // 查询职工
    try {
        Worker alice = db.findWorkerById(1);
        std::cout << "Found Alice: " << alice.name << ", Total Salary: "
                  << alice.total_salary << std::endl;
    } catch (const std::exception& e) {
        std::cerr << "Error: " << e.what() << std::endl;
    }

    // 排序职工
    db.sortWorkersByTotalSalary();
    db.displayWorkerTable();

    return 0;
}

这段代码定义了一个Worker类用于表示职工信息，以及一个WorkerDatabase类来管理职工数据库。我已实现了一些基础功能，如添加职工、查找职工、排序职工、计算平均工资等。你可以在此基础上继续开发其他功能，例如部门职工分析和输出职工信息表。

如果你在实现过程中遇到任何具体问题，比如如何读取和写入文件、如何处理用户输入、如何优化排序算法等，都可以随时向我提问。记住，编程是一个渐进的过程，多实践、多查阅资料，你会逐渐熟练起来的。祝你好运！
