结点：
包括一个数据元素及若干个指向其它子树的分支；例如，A，B，C，D等。
在数据结构的图形表示中，对于数据集合中的每一个数据元素用中间标有元素值的方框表示，一般称之为数据结点，简称结点。
在C语言中，链表中每一个元素称为“结点”，每个结点都应包括两个部分：一为用户需要用的实际数据；二为下一个结点的地址，即指针域和数据域。
数据结构中的每一个数据结点对应于一个储存单元，这种储存单元称为储存结点，也可简称结点
树结点（树节点）：
树节点相关术语：
- 节点的度：一个节点含有的子树的个数称为该节点的度；
- 叶节点或终端节点：度为0的节点称为叶节点；
- 非终端节点或分支节点：度不为0的节点；
- 双亲节点或父节点：若一个结点含有子节点，则这个节点称为其子节点的父节点；
- 孩子节点或子节点：一个节点含有的子树的根节点称为该节点的子节点；
- 兄弟节点：具有相同父节点的节点互称为兄弟节点；
- 节点的层次：从根开始定义起，根为第1层，根的子结点为第2层，以此类推；
- 堂兄弟节点：双亲在同一层的节点互为堂兄弟；
- 节点的祖先：从根到该节点所经分支上的所有节点；
- 子孙：以某节点为根的子树中任一节点都称为该节点的子孙。
根据树结点的相关定义，其属性如下：
DWORD m_dwLevel; //Node levels: starting from the root to start defining the root of the first layer, the root node is a sub-layer 2, and so on; T m_data; //the friend class can use it directly AL_TreeNode<T>* m_pParent; //Parent tree node AL_ListSingle<AL_TreeNode<T>*> m_listChild; //All Child tree node

以后的笔记潇汀会尽量详细讲解一些相关知识的，希望大家继续关注我的博客。
本节笔记到这里就结束了。
潇汀一有时间就会把自己的学习心得，觉得比较好的知识点写出来和大家一起分享。
编程开发的路很长很长，非常希望能和大家一起交流，共同学习，共同进步。
如果文章中有什么疏漏的地方，也请大家指正。也希望大家可以多留言来和我探讨编程相关的问题。
最后，谢谢你们一直的支持~~~

@brief Each of the data structure corresponds to a data node storage unit, this storage unit is called storage node, the node can
also be referred to.
The related concepts of tree node
1.degree degree node: A node of the subtree containing the number is called the node degree;
2.leaf leaf nodes or terminal nodes: degree 0 are called leaf nodes;
3.branch non-terminal node or branch node: node degree is not 0;
4.parent parent node or the parent node: If a node contains a child node, this node is called its child node's parent;
5.child child node or child node: A node subtree containing the root node is called the node's children;
6.slibing sibling nodes: nodes with the same parent node is called mutual sibling;
7.ancestor ancestor node: from the root to the node through all the nodes on the branch;
8.descendant descendant nodes: a node in the subtree rooted at any node is called the node's descendants.
////////////////////////////////Chain storage structure//////////////////////////////////////////
The computer using a set of arbitrary linear table storage unit stores data elements (which may be a continuous plurality of memory
cells, it can be discontinuous).
It does not require the logic elements of adjacent physical location is adjacent to and therefore it is not sequential storage
structure has a weakness, but also lost the sequence table can be accessed randomly advantages.
Chain store structural features:
1, compared with sequential storage density storage structure (each node consists of data fields and pointers domains, so the same
space is full, then assume full order of more than chain stores).
2, the logic is not required on the adjacent node is physically adjacent.
3, insert, delete and flexible (not the mobile node, change the node as long as the pointer).
4, find the node when stored sequentially slower than the chain stores.
5, each node is a pointer to the data fields and domains.
