1、1:#include using namespace std;class Studentpublic: void get_value() cinnumnamesex; void display( ) coutnum: numendl; coutname: nameendl; coutsex: sexageaddr; void display_1() coutage: ageendl; /引用派生类的私有成员，正确。 coutaddress: addrendl; /引用派生类的私有成员，正确。 private: int age; char addr30; ; int main() Student

2、1 stud1; stud1.get_value_1(); stud1.display(); stud1.display_1(); return 0;2:#include using namespace std;class Studentpublic: void get_value() cinnumnamesex; void display( ) coutnum: numendl; coutname: nameendl; coutsex: sexageaddr; void display_1() display(); coutage: ageendl; /引用派生类的私有成员，正确。 cout

3、address: addrendl; /引用派生类的私有成员，正确。 private: int age; char addr30; ; int main() Student1 stud1; stud1.get_value_1(); stud1.display_1(); return 0;3:#include using namespace std;class Student /声明基类public: /基类公用成员 void get_value(); void display( ); protected : /基类保护成员 int num; char name10; char sex;void

4、 Student:get_value() cinnumnamesex;void Student:display( ) coutnum: numendl; coutname: nameendl; coutsex: sexageaddr; void Student1:display1( ) coutnum: numendl; /引用基类的保护成员 coutname: nameendl; /引用基类的保护成员 coutsex: sexendl; /引用基类的保护成员 coutage: ageendl; /引用派生类的私有成员 coutaddress: addrendl; /引用派生类的私有成员 in

5、t main( ) Student1 stud1; /stud1是派生类student1类的对象 stud1.get_value_1(); /调用派生类对象stud1的公用成员函数 stud1.display1( ); /调用派生类对象stud1的公用成员函数 return 0; 4: 解法一#include using namespace std;class Student /声明基类public: /基类公用成员 void get_value(); void display( ); protected : /基类保护成员 int num; char name10; char sex;voi

6、d Student:get_value() cinnumnamesex;void Student:display( ) coutnum: numendl; coutname: nameendl; coutsex: sexageaddr; void Student1:display1( ) coutnum: numendl; /引用基类的保护成员，合法 coutname: nameendl; /引用基类的保护成员，合法 coutsex: sexendl; /引用基类的保护成员，合法 coutage: ageendl; /引用派生类的私有成员，合法 coutaddress: addrendl; /

7、引用派生类的私有成员，合法 int main( ) Student1 stud1; /stud1是派生类student1类的对象 stud1.get_value_1(); /调用派生类对象stud1的公用成员函数get_value_1 stud1.display1( ); /调用派生类对象stud1的公用成员函数display1 return 0; 解法二#include using namespace std;class Student /声明基类public: /基类公用成员 void get_value(); void display( ); protected : /基类保护成员 in

8、t num; char name10; char sex;void Student:get_value() cinnumnamesex;void Student:display( ) coutnum: numendl; coutname:nameendl; coutsex:sexageaddr; void Student1:display1( ) coutage:ageendl; coutaddress:addrendl; int main( ) Student1 stud1; /stud1是派生类student1类的对象 stud1.get_value(); stud1.get_value_

9、1(); stud1.display( ); stud1.display1(); /合法。display1是派生类中的公用成员函数 return 0; 5：class A /A为基类public: void f1( ); int i; protected: void f2(); int j; private: int k;class B: public A /B为A的公用派生类public: void f3( ); protected: int m; private: int n;class C: public B /C为B的公用派生类public: void f4(); private: i

10、nt p;int main()A a1; /a1是基类A的对象 B b1; /b1是派生类B的对象 C c1; /c1是派生类C的对象 return 0;6：#include using namespace std;class Apublic: void f1( ); protected: void f2(); private: int i;class B: public Apublic: void f3( ); int k; private: int m;class C: protected Bpublic: void f4(); protected: int n; private: int
