#include <iostream>

        int V;

建议你再学习下C++参数传递的三种方式……

程序代码：

#include <iostream>
using namespace std;
class Chang//类名我用的大写
{
public:
    Chang(int h ,int w,int l)
    {
        height=h;
        wide=w;
        lon=l;
    }
    int volume();

private:
    int height;
    int wide;
    int lon;

};

int Chang::volume()//这里是函数声明
{
    return (height*wide*lon);
}

int main()
{
    Chang v1(1,2,3);//构造函数
    cout <<"the volume is :"<<v1.volume()<<endl;

        return 0;
}
