C++源代码单词扫描程序（词法分析）

功能：



（1）C++源代码扫描程序识别C++记号。

C++语言包含了几种类型的记号：标识符，关键字，数（包括整数、浮点数），字符串、注释、特殊符号（分界符）和运算符号等。

（2）打开一个C++源文件，打印出所有以上的记号。

（3）要求应用程序应为Windows界面。

（4）选作部分：为了提高C++源程序的可读性，C++程序在书写过程中加入了空行、空格、缩进、注释等。假设你想牺牲可读性，以节省磁盘空间，那么你可以存贮一个删除了所有不必要空格和注释的C++源程序的压缩文本。因此，程序中还应该有这样的压缩功能。

（5）选作部分：进一步思考或实现——如何进一步实现减小源文件大小的压缩功能。

（6）应该书写完善的软件文档。

-C++ source code word Scanner (lexical analysis) functions: (1) C++ source code scanner to identify C++ mark. C++ language includes several types of tokens: identifiers, keywords, numbers (including integer, floating point), strings, comments, special symbols (delimiters), and operation symbols. (2) Open a C++ source file, print out all of the above marks. (3) requires that the application should be Windows interface. (4) is selected as the section: C++ source in order to improve readability, C++ program in the writing process by adding a blank line, space, indentation, comments, and so on. Suppose you want to sacrifice readability, to save disk space, you can store a compressed text deleted all unnecessary whitespace and comments C++ source program. Therefore, the program also should have such compression. (5) is selected as the section: further consideration or implementation- how to further achieve a reduction in the size of the source file compression functions. (6) should write per
