这是一个Python的类定义。其中包括了一个Person类和一个继承自Person类的Student类。

Person类包括了初始化方法__init__()，其中有name和age两个参数，并将这两个参数分别赋值给实例变量self.name和self.age。同时，它还包括了setName()和setAge()两个方法，用来修改实例变量name和age的值。最后，show()方法用来打印实例变量的值。

Student类继承了Person类，所以它也有name和age两个实例变量。此外，它还有一个major实例变量，它在初始化函数__init__()中被赋值。同时，它还有一个setMajor()方法来修改major的值。最后，它覆盖了Person类的show()方法，并在其中调用了Person类的show()方法来打印name和age的值，再打印出major的值。

抱歉，这段代码不是 C++ 代码，而是 Python 代码。可以参考下面的完整代码：

class Person:
    def __init__(self, name, gender, age, profession):
        self.name = name
        self.gender = gender
        self.age = age
        self.profession = profession
    
    def set_name(self, name):
        self.name = name
    
    def set_gender(self, gender):
        self.gender = gender
    
    def set_age(self, age):
        self.age = age
    
    def set_profession(self, profession):
        self.profession = profession
    
    def display_name(self):
        print("Name:", self.name)
    
    def display_gender(self):
        print("Gender:", self.gender)
    
    def display_age(self):
        print("Age:", self.age)
    
    def display_profession(self):
        print("Profession:", self.profession)
    
    def display_all(self):
        self.display_name()
        self.display_gender()
        self.display_age()
        self.display_profession()

class Student(Person):
    def __init__(self, name, gender, age, profession, school, major, grade):
        super().__init__(name, gender, age, profession)
        self.school = school
        self.major = major
        self.grade = grade
    
    def set_school(self, school):
        self.school = school
    
    def set_major(self, major):
        self.major = major
    
    def set_grade(self, grade):
        self.grade = grade
    
    def display_school(self):
        print("School:", self.school)
    
    def display_major(self):
        print("Major:", self.major)
    
    def display_grade(self):
        print("Grade:", self.grade)
    
    def display_all(self):
        super().display_all()
        self.display_school()
        self.display_major()
        self.display_grade()

person1 = Person("Alice", "Female", 25, "Engineer")
person1.display_all()

student1 = Student("Bob", "Male", 20, "Student", "XYZ University", "Computer Science", "Sophomore")
student1.display_all()

这个代码定义了两个类：`Person` 和 `Student`，其中 `Student` 是 `Person` 的子类。`Person` 类有四个属性：姓名、性别、年龄、职业，以及相应的 getter 和 setter 方法。`Student` 类在 `Person` 的基础上增加了三个属性：学校、专业、年级，也有相应的 getter 和 setter 方法。同时，`Student` 类重写了 `display_all()` 方法，打印出所有属性，包括父类属性和子类属性。

在代码的最后，创建了一个 `Person` 对象和一个 `Student` 对象，分别调用了它们的 `display_all()` 方法，打印出所有属性。

class Person: def __init__(self,name,PID,sex,age): self.name=name self.PID=PID self.sex=sex self.age=age def getname(self): return self.name def getPID(self): return self.PID def getsex(self): return self.sex def getage(self): return self.age def getinfo(self): return self.name,self.PID,self.sex,self.age def setname(self,name): self.name=name def setID(self,PID): self.PID=PID def setsex(self,sex): self.sex=sex def setage(self,age): self.age=agedef setinfo(self,name,PID,sex,age): self.name=name self.PID=PID self.sex=sex self.age=age class Ustudent(Person): #重写构造函数 def __init__(self,name,PID,sex,age,school): super().__init__(name,PID,sex,age) self.school=school def getschool(self): return self.school #重写 getinfo 函数 def getinfo(self): return self.name,self.PID,self.sex,self.age,self.school #重写 setinfo 函数 def setinfo(self,name,PID,sex,age,school): #self.name=name #self.PID=PID #self.sex=sex #self.age=age super().setinfo(name,PID,sex,age) def setschool(self,school): self.school=school p=Person("zjhong","3307217305256314","M",19) print(p.getinfo()) s=Ustudent("zjh","3307217305256313","M",20,"湖州师院学院") p.setinfo("zhangjh","3307217305256315","F",18) print(s.getinfo()) print(p.getinfo()) s.setinfo("zhangjianh","3307217305256316","F",21,"湖州学院") print(s.getinfo()) #调用父类继承函数 setname s.setname("lisi") s.setschool("湖州师范学院") print(s.getinfo()) print(p.getinfo())

这段代码定义了两个类：Person和Ustudent，Person类有name、PID、sex、age属性和getinfo、setinfo、getname、getPID、getsex、getage方法，Ustudent类继承了Person类，并新增了school属性和getschool、setschool方法。代码中还进行了一些属性设置和方法调用的操作，你想问什么问题呢？
