答案-c++面向对象程序设计课后习题答案(谭浩强版)

{ int i;

for (i=0;i<10;i++) cin>>array[i]; }

void Array_max::max_value() {int i;

max=array[0]; for (i=1;i<10;i++)

if(array[i]>max) max=array[i]; }

void Array_max::show_value() {cout<<\ }

6：解法一

#include using namespace std; class Box {public:

void get_value(); float volume(); void display(); public:

float lengh; float width; float height; };

void Box::get_value()

{ cout<<\ cin>>lengh; cin>>width; cin>>height; }

float Box::volume()

{ return(lengh*width*height);}

void Box::display()

{ cout<

int main()

{Box box1,box2,box3; box1.get_value();

cout<<\ box1.display(); box2.get_value();

cout<<\ box2.display(); box3.get_value();

cout<<\ box3.display(); return 0; }

解法二：

#include using namespace std; class Box {public:

void get_value(); void volume(); void display(); public:

float lengh; float width; float height; float vol; };

void Box::get_value()

{ cout<<\ cin>>lengh; cin>>width; cin>>height; }

void Box::volume()

{ vol=lengh*width*height;}

void Box::display() { cout<

int main()

{Box box1,box2,box3; box1.get_value();

box1.volume();

cout<<\ box1.display(); box2.get_value(); box2.volume();

cout<<\ box2.display(); box3.get_value(); box3.volume();

cout<<\ box3.display(); return 0; }

#include using namespace std; class Date {public:

{cout<

Date d3(10); Date d4; d1.display(); d2.display(); d3.display(); d4.display(); return 0; } 4:

#include using namespace std; class Student {public:

Student(int n,float s):num(n),score(s){} void display(); private: int num; float score; };

void Student::display()

{cout<

int main()

{Student stud[5]={

Student(101,78.5),Student(102,85.5),Student(103,98.5), Student(104,100.0),Student(105,95.5)}; Student *p=stud;

for(int i=0;i<=2;p=p+2,i++) p->display(); return 0; } 5:

#include using namespace std; class Student {public:
