ic读写源代码，创建文件、读、写等功能的简单实现。(Source code of IC card IO)

用于文件的传输和接收的测试程序，可以实现多个文件和文件夹的传输(For file transmission and reception of the test procedure can be achieved a number of files and folders transmission)

说明：  能够对dxf文件进行读取,而且是源代码哦(can read the .dxf file)

首先通过文件操作，读取文件内容，把字符逐个提取后统计字符频率，建立哈夫曼树和进行哈夫曼编码，当然这是根据ASCII编码来将字符转换为二进制，然后实现前缀编码，然后把编码后的使用二进制流写入相应文件(First through file operations, read the file content, the characters one by one after extracting character frequency statistics, establish a Huffman tree and Huffman encoding, and, of course, this is according to ASCII code to convert characters to the binary, then realize the prefix encoding, and then the encoded using binary stream into the corresponding files )

读取行情的def文件的例子，并保存到数据库了，包含了两个行情数据库，上海和深圳的。(Quotes of the def file to read the example, and saved to the database, and contains two Quotes databases, Shanghai and Shenzhen.)

绘制描述事件先后顺序的前驱图，可以拖动现有结点的位置，与该结点相连的有向边也随之移动；可以将前驱图存入文件，从文件中取出(Drawing description of the event sequence of the precursor Figure)

读取两个文件，比较其中的相同单词和出现次数及频率，并将结果保存到文件(Read the two documents, which compare the same words and the number and frequency of appearance, and save the results to a file)

说明：  实现堆栈的操作，功能为入栈、出栈，实现先进后出的原则(to realize the stack operation , the function :push onto the stack out the stack )

说明：  可以在后台复制U盘的所有文件。可以自己修改哦(U disk can copy all the files in the background. Oh, can modify their own)

在文件列表中列出所有选定的文件类型 双击显示图片(Listed in the file list of all the selected file type double-click Display images)
