本文介绍如何使用C++编程语言计算长方体的体积和面积，通过输入长、宽、高，程序自动计算并输出结果。

#include<iostream>
using namespace std;
class Bulk
{
private:
    double dLength;
    double dWidth;
    double dHeight;
public:
    void getBulk(double,double,double);
    double volume();
    double area();
};
void Bulk::getBulk(double a,double b,double c)
{
    dLength=a;
    dWidth=b;
    dHeight=c;
}
double Bulk::volume()
{
    double dVolume;
    dVolume=dLength*dWidth*dHeight;
    return dVolume;
}
double Bulk::area()
{
  double dArea;
  dArea=2*(dLength*dWidth+dLength*dHeight+dWidth*dHeight);
  return dArea;
}
int main()
{
    Bulk*t;
    t=new Bulk;
    double dLength,dWidth,dHeight;
    cout<<"请输入长方形的长";
    cin>>dLength;
    cout<<"请输入长方形的宽";
    cin>>dWidth;
    cout<<"请输入长方形的高";
    cin>>dHeight;
    t->getBulk(dLength,dWidth,dHeight);
    cout<<"该长方体的体积为";
    cout<<t->volume();
    cout<<"该长方体的面积为";
    cout<<t->area();
    delete t;
    return 0;
}
