可以实现两个大整数（不限数位）相加减！ 在C＋＋中，加减法的两个数必须在系统规定内，本程序突破了这一界限！-can achieve two large integers (Open-digit) is modified! In C++, and subtract the number two must be within the system, the process broke the limits!

 ；文件O显示：读取数据从文件和cab可以传输您想要的格式。

一个递归算法,并把递归出的文件隐藏,使用VB开发,希望大家支持-A recursive algorithm, and recursive documents are hidden, use the VB development, I hope you will support

这是我上个学期操作系统的课程设计，做了一个多级文件系统，用文件模拟磁盘，基于i节点结构，功能超强，希望对大家有用。-This is my last semester of courses operating system design and a multi-level file system, disk using simulated document, based on i node structure, function superpower, we hope that the right useful.

题目：设计一个题目，演示用算符优先法对算术表达式求值的过程。 概要设计 1、顺序扫描中缀算术表达式，当读到数字时直接将其送至输出队列中； 2、当读到运算符时，将栈中所有优先级高于或等于该运算符弹出，送至输出队列中，再将当前运算符入栈； 3、当读入左括号时，即入栈； 4、当读到右括号时，将靠近栈顶的第一个左括号上面的运算符全部一次弹出，送至输出队列中，再删除栈中的左括号。 5、使用VS栈来存储读入的操作和运算结果，然后进行数字字符到数值的转换。 -Title: Design of a topic, presentation operator priority method with arithmetic expression evaluation process. Summary of design 1, the order of scanning arithmetic infix expressions, when they read numbers directly to the output queue 2, when they read operator, it will stack all priority higher than or equal to the operator pop-up , sent to the output queue, and then the current operator入栈 3, when read left brackets, that is, when入栈 4, when they read the right brackets, it will be near the Top-left of the first operator in brackets above All a pop-up, sent to the output queue, and then delete stacks of left brackets. 5, the use of VS stack to store read operation and computing the results of numeric characters and then proceed to the numerical co
