python编程求长方体体积_定义一个类,计算长方体的体积

#include &ltiostream&gt

using namespace std;

class box

{

private:

float length;

float width;

float height;

public:

box(float a,float b,float c);

void volume();

};

box::box(float a,float b,float c)

{

length=a;

width=b;

height=c;

}

void box::volume()

{

cout&lt&lt"长方体的体积是："&lt&ltlength*width*height&lt&ltendl;

}

void main()

{

float a,b,c;

cout&lt&lt"请输入长方体的长：";

cin&gt&gta;

cout&lt&lt"请输入长方体的宽：";

cin&gt&gtb;

cout&lt&lt"请输入长方体的高：";

cin&gt&gtc;

box chang(a,b,c);

chang.volume();

}
