定义类CPerson，它有以下属性：姓名、身份证号、性别、年龄、和相应的成员函数（无构造函数）。再利用CPerson派生出类CEmployee，派生类CEmployee增加了两个表示部门和薪水的数据成员，根据需要为派生类增加新的成员函数。

class CPerson:
def __init__(self, name, id_card, gender, age):
self.name = name
self.id_card = id_card
self.gender = gender
self.age = age

class CEmployee(CPerson):
def __init__(self, name, id_card, gender, age, department, salary):
super().__init__(name, id_card, gender, age)
self.department = department
self.salary = salary

def get_department(self):
return self.department

def get_salary(self):
return self.salary

# 可以根据需要添加其他成员函数

# 示例用法
person = CPerson("John", "1234567890", "Male", 30)
employee = CEmployee("Jane", "0987654321", "Female", 35, "HR", 5000)

print(person.name) # Output: John
print(employee.get_department()) # Output: HR
print(employee.get_salary()) # Output: 5000
