第5讲 类和对象的高级应用-对象数组

对象数组

#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(),        Box(15,18),        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;    return 0;}
