程序结果太长。热情抓的图看不了后面。我就帮他抓了后面的。大家上机运行去，就知道书上的和这个那个才是经典了

请问我怎么运行的时候有错误啊？ --------------------Configuration: 二叉数 - Win32 Debug-------------------- Compiling... 二叉数.C H:\shujujiegou\二叉数.C(1) : fatal error C1083: Cannot open include file: 'tree.h': No such file or directory Error executing cl.exe.

二叉数.OBJ - 1 error(s), 0 warning(s) 这是说我的ＩＮＣＵＤＥ头文件里没有这种文件啊？

呵呵。热情的我试过了。你要把他搞成三个头文件。你看清楚他发的。他那里有注释的。。。他写的我运行得出结果就抓图上来了~~~~~~我寒~~~~~~你看清楚你自己建立的工程。c++的你也拿去c运行。强~~~~~~~i  fu  you

大家最好用。。。。。。。我和热情是用这个来运行的

多谢大哥了，我对数据结构也太熟，所以这些我可以参考学习。

谁能把这个在2005下面编译一下啊??
怎么我看不到贴图得输出结果?

在编译下面一断时出错：
StackNode(const T &item,StackNode<T> *perNext=NULL);
~StackNode(){};
friend class LinStack<T>;
};
template<typename T>StackNode<T>::StackNode(const T &item,StackNode<T> *perNext=NULL){
data=item;
next=perNext;
}

错误信息如下：
d:\my c++\经典\linstack.h(17) : error C2572: 'StackNode<T>::StackNode<T>' : redefinition of default parameter : parameter 2
d:\my c++\经典\linstack.h(10) : see declaration of 'StackNode<T>::StackNode<T>'
执行 cl.exe 时出错.


为什么？！使用VC++6.0

LZ,可不可以帮我写个类似的,不过是用C语言写二叉树的仿真指针的基本操作;
二叉树的仿真指针的结构可定义如下：
struct btree {
{ elemtype data;//存放结点值
int lchild,rchild;//存放左、右孩子的数组元素的下标
}
你就给我写个创建二叉树和输出二叉树,其实我是对仿真不了解,呵呵...
麻烦了,写好可以发到我的邮箱qingting5201314@126.com
或者加我ＱＱ：４２０９２２９４１给我讲解下更好，嘿嘿
