该程序使用C++写的一个基于递归子程序算法的语法翻译器，是在vs2012环境下编写的，供大家参考和学习(The program uses C++ to write an algorithm based on recursive subroutine syntax interpreter is written in vs2012 environment, for your reference and learning)

一个压缩软件的SDK，有例子！ 请大家尝试！(a packer software sdk)

能够实现AES加密解密的功能，已经过测试可以使用(Enables AES encryption and decryption functions, have been tested can be used)

使用某种高级语言和LEX实现一个C语言子集的词法分析器，即从输入的源程序中，识别出各个具有独立意义的单词，滤掉空格和注释。依次输出各个单词的内部编码及单词符号自身值。（遇到错误时可显示“Error”，然后跳过错误部分继续显示）。其中空白符、制表符和换行符均视为空格，用来分隔单词，注释包括两种形式：/*…*/和//。(Use some kind of high-level language and the LEX lexical analyzer to achieve a C language subset from the input source to identify each word has an independent significance, filter out the whitespace and comments. Followed by the output of the internal encoding of each word and word symbols value. (Displayed when an error is encountered "Error", then skip the error part of the display). Where whitespace, tabs and line breaks are treated as spaces, used to separate words, annotation, including two forms :/* ...*/and//. )

DES加密方法加密BMP图像，CBC方式实现。(DES encryption methods encryption BMP image, CBC way.)

该文件能用Visual C++6.0打开编译实现加密解密功能，并能通过少量的修改改(修改处程序源码中已标明)镶嵌到其他的程序源码中实现加密解密功能。 可直接使用。 (The file can use Visual C++6.0 to open compiled encryption and decryption functions through a few modifications reform (modify at program source code has been marked) inlaid into the other program source code to achieve encryption and decryption functions. Can be used directly.)

哈夫曼编码，基于MFC开发。哈夫曼编码为熵编码中的最佳方法之一，广泛用于各种数据压缩技术中。-Huffman coding, based on the MFC. Huffman coding for entropy coding one of the best ways, for a wide variety of data compression technology.
