c+实验8 继承与派生上机练习题 - 1. 定义一个哺乳动物类Mammal，并从中派生出一个狗类Dog，下面给出Mammal类的定义，要求： 1 添加Dog类的颜色数据成员，访问属性为私有，通过SetColor和GetColor成员函数来对颜色进展设置和获取。 2 分别为基类和派生类添加相应的构造函数有参、无参和析构函数，并进展测试。 class Mammal protected: int itsAge; int itsWeight; public: int GetAgereturn itsAge; void SetAge(int age) itsAge=age; int GetWeight return itsWeight; void SetWeight(int weight) itsWeight= weight; ; class Dog : public Mammal /定义Dog类的数据成员和成员函数 ; 改: #include #include using namespace std; class Mammal protected: int itsAge; int itsWeight; public: Mammal; Mammal; int GetAgereturn itsAge; void SetAge(int age) itsAge=age; int GetWeight return itsWeight; void SetWeight(int weight) itsWeight= weight; ; class Dog : public Mammal protected: char itscolor20; public: Dog; void Setcolor(char *color) strcpy(itscolor,color); void getcolorcoutage1; SetAge(age1); coutweight1; SetWeight(weight1); Mammal:Mammal coutcolor;Setcolor(color); cout #include using namespace std; #define n 20 /类的定义 class Person protected: char namen; char sexn; int age; public: Person; void setperson; void displayperson; ; class Teacher :virtual public Person protected: char jobn; char roomn; char subjectn; public : Teacher; void setteacher; void displayteacher; ; class Student:virtual public Person protected: char majorn; char banjin; int leibie; public : Student; void setstudent; void displaystudent; ; class Postdoctor:public Teacher,public Student public : Postdoctor; void setpostdoctor; void displaypostdoctor; ; /构造函数 Person:Person setperson; Teacher:Teacher setteacher; Student:Student setstudent; Postdoctor:Postdoctor /设置数据/ void Person:setperson coutname; coutsex; coutage; void Teacher:setteacher coutjob; coutroom; coutsubject; void Student:setstudent coutmajor; coutbanji; coutleibie; /数据显示/ void Person:displayperson cout姓名:性别:年龄: void Teacher:displayteacher displayperson; cout职称:教研室:所授课程: void Student:displaystudent displayperson; cout专业:班级:类别: void Postdoctor:displaypostdoctor displayperson; cout职称:教研室:所授课程:专业:班级:类别:博士后 / void main cout您正在输入一个教师的信息:Teacher t1; cout*syy割cout您正在输入一个学生的信息:Student s1; cout*syy割cout您正在输入一个博士后的信息:Postdoctor p1; p1.displaypostdoctor; 第 5 页 共 5 页
