基于Visual C++的一个二叉树的程序，能实现从文件输入和数组两种方法建立二叉树，实现二叉树的前，中，后序遍历，广义表形式的输出，结点个数的统计，结点度的计算，树的高度计算，最大值的计算。-he establishment of the two fork tree　the file input and an array of two methods, the realization of the two binary tree before, after the traversal, the output of generalized form, statistics the number of nodes, node degree, calculate the height of tree, the calculation of the maximum value.
