如何添加include文件？

Question

//liumengyang.h

#include<iostream.h>
class liumengyang
{
private:
int t;
public:
int v(int l1,int h1,int s1);
};
int liumengyang::v(int l1,int h1,int s1)
{
t=l1*h1*s1;
return t;
}
#include<liumengyang.h>

main()
{
int s;
liumengyang zhangjingchu(1,2,3);
s=zhangjingchu.v;
cout<<s;
}
我这个程序怎么错了 各位高手，能帮忙看看么？编译提示错误：D:\软件\MSDev98\MyProjects\include\include.cpp(16) : fatal error C1083: Cannot open include file: 'liumengyang.h': No such file or directory
执行 cl.exe 时出错.
这个是怎么回事？还有 如何不在程序中通过“//”添加.h文件 而在文件夹中直接添加include 文件呢？谁能告诉我，谢谢

类有问题，看看下述修改后代码：//liumengyang.h#include<iostream>using namespace std;class liumengyang{private:int t;public:int v(int l1,int h1,int s1);};int liumengyang::v(int l1,int h1,int s1){t=l1*h1*s1;return t;}#include “liumengyang.h”int s;liumengyang zhangjingchu;s=zhangjingchu.v(1,2,3);cout<<s;&nbsp;抢首赞&nbsp;&nbsp;&nbsp;&nbsp;评论&nbsp;分享&nbsp;举报
