按RNL顺序打印二叉树，一道数据结构上机题-print binary tree in RNL order

将二叉堆树 在控制台下 调用 api 函数 用 图形树打印，-The binary tree in the control of the tree with graphic print

用c实现的一个对二叉树的各种操作，包括插入删除等的源代码程序，编译已通过。-A binary tree with c a variety of operations, including the insertion and deletion program source code, the compiler has passed.

在控制台树形输出二叉树，使用了队列。首先设置叶子节点间的间距，然后以坐标的形似记录下每个节点的位置-Binary output in the console tree, using a queue. The spacing between the first set of leaf nodes, then the coordinates of the shape of the recording position of each node
