对象数组应用实例

#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;
}
