用c++写一个使用顺序表的员工管理系统

好的，以下是一个简单的使用顺序表实现员工管理系统的C++代码：

#include <iostream>
#include <cstring>

using namespace std;

const int MAX_SIZE = 100; // 最大员工数量

// 员工结构体
struct Employee {
    int id; // 员工编号
    char name[20]; // 员工姓名
    int age; // 员工年龄
    char gender; // 员工性别
};

// 员工管理系统类
class EmployeeManagementSystem {
public:
    EmployeeManagementSystem() : size(0) {} // 构造函数，初始员工数量为0
    ~EmployeeManagementSystem() {} // 析构函数

    void addEmployee(); // 添加员工
    void deleteEmployee(); // 删除员工
    void modifyEmployee(); // 修改员工信息
    void searchEmployee(); // 查找员工信息
    void displayAllEmployees(); // 显示所有员工信息

private:
    Employee employees[MAX_SIZE]; // 员工数组
    int size; // 员工数量
};

void EmployeeManagementSystem::addEmployee() {
    if (size >= MAX_SIZE) {
        cout << "员工数量已达到上限，无法添加新员工！" << endl;
        return;
    }

    Employee e;
    cout << "请输入员工编号：";
    cin >> e.id;
    cout << "请输入员工姓名：";
    cin >> e.name;
    cout << "请输入员工年龄：";
    cin >> e.age;
    cout << "请输入员工性别（M/F）：";
    cin >> e.gender;

    employees[size++] = e; // 将新员工添加到数组末尾
    cout << "添加成功！" << endl;
}

void EmployeeManagementSystem::deleteEmployee() {
    if (size == 0) {
        cout << "员工列表为空，无法删除员工！" << endl;
        return;
    }

    int id;
    cout << "请输入要删除的员工编号：";
    cin >> id;

    int index = -1;
    for (int i = 0; i < size; i++) {
        if (employees[i].id == id) {
            index = i;
            break;
        }
    }

    if (index == -1) {
        cout << "未找到要删除的员工！" << endl;
        return;
    }

    for (int i = index; i < size - 1; i++) {
        employees[i] = employees[i + 1]; // 将后面的员工向前移动
    }

    size--; // 员工数量减1
    cout << "删除成功！" << endl;
}

void EmployeeManagementSystem::modifyEmployee() {
    if (size == 0) {
        cout << "员工列表为空，无法修改员工信息！" << endl;
        return;
    }

    int id;
    cout << "请输入要修改的员工编号：";
    cin >> id;

    int index = -1;
    for (int i = 0; i < size; i++) {
        if (employees[i].id == id) {
            index = i;
            break;
        }
    }

    if (index == -1) {
        cout << "未找到要修改的员工！" << endl;
        return;
    }

    Employee e;
    cout << "请输入员工姓名（原值为" << employees[index].name << "）：";
    cin >> e.name;
    cout << "请输入员工年龄（原值为" << employees[index].age << "）：";
    cin >> e.age;
    cout << "请输入员工性别（M/F，原值为" << employees[index].gender << "）：";
    cin >> e.gender;

    e.id = id;
    employees[index] = e; // 将修改后的员工信息替换原有信息
    cout << "修改成功！" << endl;
}

void EmployeeManagementSystem::searchEmployee() {
    if (size == 0) {
        cout << "员工列表为空，无法查找员工信息！" << endl;
        return;
    }

    int id;
    cout << "请输入要查找的员工编号：";
    cin >> id;

    int index = -1;
    for (int i = 0; i < size; i++) {
        if (employees[i].id == id) {
            index = i;
            break;
        }
    }

    if (index == -1) {
        cout << "未找到要查找的员工！" << endl;
        return;
    }

    Employee e = employees[index];
    cout << "员工编号：" << e.id << endl;
    cout << "员工姓名：" << e.name << endl;
    cout << "员工年龄：" << e.age << endl;
    cout << "员工性别：" << e.gender << endl;
}

void EmployeeManagementSystem::displayAllEmployees() {
    if (size == 0) {
        cout << "员工列表为空！" << endl;
        return;
    }

    cout << "员工列表：" << endl;
    for (int i = 0; i < size; i++) {
        Employee e = employees[i];
        cout << "员工编号：" << e.id << endl;
        cout << "员工姓名：" << e.name << endl;
        cout << "员工年龄：" << e.age << endl;
        cout << "员工性别：" << e.gender << endl;
    }
}

int main() {
    EmployeeManagementSystem ems;

    while (true) {
        cout << "请选择操作：" << endl;
        cout << "1. 添加员工" << endl;
        cout << "2. 删除员工" << endl;
        cout << "3. 修改员工信息" << endl;
        cout << "4. 查找员工信息" << endl;
        cout << "5. 显示所有员工信息" << endl;
        cout << "6. 退出" << endl;

        int choice;
        cin >> choice;

        switch (choice) {
            case 1:
                ems.addEmployee();
                break;
            case 2:
                ems.deleteEmployee();
                break;
            case 3:
                ems.modifyEmployee();
                break;
            case 4:
                ems.searchEmployee();
                break;
            case 5:
                ems.displayAllEmployees();
                break;
            case 6:
                return 0;
            default:
                cout << "无效操作！" << endl;
        }

        cout << endl;
    }

    return 0;
}

这个员工管理系统使用顺序表来存储员工信息，可以添加、删除、修改、查找和显示所有员工信息。运行时，会显示一个菜单供用户选择操作，直到用户选择退出为止。
