read-and-write-CSV-file

说明：  

文件修改的监视(The example of monitoring the change of files)

说明：  用数组和结构体实现保存文件，录入内容为所有同学的学号、姓名、语文成绩和数学成绩(Structure with the array and achieve the goal of preserving documents, recording the content for all students of the school number, name, language and mathematics achievement)

这个源代码实现了对pdf文件的读取，可以通过此程序将pdf转化为文本模式。(The source code to achieve the PDF file to read, through this procedure will be converted to text mode pdf.)

Visual C++案例开发集锦第七章\文件分割的程序源码,值得一看！(Visual C++ case development highlights Chapter File Splitter program source code, worth a visit!)

说明：  日常工作中用于拆分文件中数据和统计工作量的小程序(Daily work for the Resolution of the document the workload of data and statistics applets)

使用CArchive类对文件进行操作。对VC操作会更熟悉。(CArchive Class used to operate on the document. On the VC will be more familiar with the operation.)

文件输入物品税前价格，通过相应物品的税率计算出物品的售价并显示。(File input goods before prices, tax rates by the corresponding articles of the items priced and displayed.)

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 )

演示内存映射文件的使用，对内存映射文件作了详细说明(demo memory map documents the use of memory mapping document elaborated)
