编写一个职工工资管理系统的程序代码

好的，以下是一个简单的职工工资管理系统的程序代码，使用Python语言编写：

# 定义职工类
class Employee:
    def __init__(self, name, id, salary):
        self.name = name
        self.id = id
        self.salary = salary

    def display_employee(self):
        print(f"Name: {self.name}, ID: {self.id}, Salary: {self.salary}")

# 定义职工管理类
class EmployeeManager:
    def __init__(self):
        self.employees = []

    # 添加职工
    def add_employee(self, employee):
        self.employees.append(employee)

    # 显示所有职工信息
    def display_all_employees(self):
        for employee in self.employees:
            employee.display_employee()

    # 根据ID查找职工信息
    def find_employee_by_id(self, id):
        for employee in self.employees:
            if employee.id == id:
                employee.display_employee()
                return
        print("Employee not found.")

    # 根据ID删除职工
    def delete_employee_by_id(self, id):
        for employee in self.employees:
            if employee.id == id:
                self.employees.remove(employee)
                return
        print("Employee not found.")

    # 修改职工工资
    def modify_employee_salary(self, id, new_salary):
        for employee in self.employees:
            if employee.id == id:
                employee.salary = new_salary
                return
        print("Employee not found.")

# 测试代码
if __name__ == "__main__":
    manager = EmployeeManager()

    employee1 = Employee("John", 1001, 5000)
    employee2 = Employee("Alice", 1002, 6000)
    employee3 = Employee("Bob", 1003, 7000)

    manager.add_employee(employee1)
    manager.add_employee(employee2)
    manager.add_employee(employee3)

    manager.display_all_employees()

    manager.find_employee_by_id(1002)

    manager.modify_employee_salary(1001, 5500)
    manager.display_all_employees()

    manager.delete_employee_by_id(1003)
    manager.display_all_employees()

以上代码实现了一个简单的职工工资管理系统，可以添加、查找、修改和删除职工信息。
