[C]C++程序设计第三版第九章 对象数组
9.6 输入三个立方体体积，用对象数组的方法
#include<iostream>
using namespace std;
class Box
{
public:
Box(int h =10,int w =12,int len = 15 ):height(h),width(w),length(len){}
int volume();
private:
int height;
int width;
int length;
};
int Box ::volume()
{
return(height*width*length);
}
int main()
{
Box a[3] = {
Box(10,12,15),
Box(15,18,20),
Box(16,20,26)
};
cout<<"volume of a[0] is"<<a[0].volume()<<endl;
cout<<"volume of a[1] is"<<a[1].volume()<<endl;
cout<<"volume of a[2] is"<<a[2].volume()<<endl;
getchar();
}
using namespace std;
class Box
{
public:
Box(int h =10,int w =12,int len = 15 ):height(h),width(w),length(len){}
int volume();
private:
int height;
int width;
int length;
};
int Box ::volume()
{
return(height*width*length);
}
int main()
{
Box a[3] = {
Box(10,12,15),
Box(15,18,20),
Box(16,20,26)
};
cout<<"volume of a[0] is"<<a[0].volume()<<endl;
cout<<"volume of a[1] is"<<a[1].volume()<<endl;
cout<<"volume of a[2] is"<<a[2].volume()<<endl;
getchar();
}
、 9.9 讲一个立方体对象的值赋给另一个立方体对象
#include<iostream>
using namespace std;
class Box
{
public:
Box(int h =10,int w =12,int len = 15 );
int volume();
private:
int height;
int width;
int length;
};
Box :: Box(int h, int w, int len)
{
height =h;
width =w;
length =len;
}
int Box ::volume()
{
return(height*width*length);
}
int main()
{
Box box1(15,30,25),box2;
cout<<"The volume of box1 is"<<box1.volume()<<endl;
cout<<"The volume of box2 is"<<box2.volume()<<endl;
getchar();
return 0;
}
