C++经典大整数实现,加减乘除.输入输出

QT和FireBird的入门程序，FireBird是一个开源的轻量级数据库管理系统，可在Linux,Unix,MacOS,Windows,Solaris系统下运行。包括源文件和说明文档。-This article is the description of the first steps in setting QT, Visual Studio and FireBird. It may be useful for those, who just start working with database FireBird Embedded by means of QT provider. The article will be also helpful for the developers who just start working with QT.

假设以如下说明的三元组 (F、C、L/R) 序列输入一棵二叉树的诸边(其中 F 表示双亲结点的标识，C 表示孩子结点标识，L/R 表示 C 为 F 的左孩子或右孩子)，且在输入的三元组序列中，C 是按层次顺序出现的。设结点的标识是字符类型。F=‘＾’时 C 为根结点标识，若 C 亦为‘＾’，则表示输入结束。试编写算法，由输入的三元组序列建立二叉树的二叉链表,并以中序序列输出。^AL ABL ACR BDL CEL CFR DGR FHL ^^L -Assuming the following description of the triple (F, C, L/R) sequence of a binary tree of all the input side (where F that identifies the parent node, C, said child node ID, L/R that C is F, left or right child child), and triples in the input sequence, C is the emergence of a hierarchical order. Node identity is established character types. F = " ^" C for the root identity when, if C is also a " ^" , then enter the end. Test preparation algorithm, the input sequence of triples binary build the binary tree list, and in order to sequence the output
