box.cpp

这是我上学时的C＋＋实验。。。 里面包含了类的应用

#include <iostream.h>

class box
{
public:
	box(double aa=0,double bb=0,double cc=0)
	{
		length=aa;
		width=bb;
		hight=cc;
		V=aa*bb*cc;
	}
	void vol()
	{
		cout<<"此盒子体积是:"<<endl;
		cout<<V<<endl;
	}
private:
	double length,width,hight,V;
};

int main()
{
	box mybox(1,2,3);
	mybox.vol();

	return 0;
}
