[Other] lexical_analysis_program DL : 0: 编译原理、词法分析程序。题目：词法分析程序的设计和实现实验内容：设计并实现C语言的词法分析程序，要求如下。 (1)可以识别出用Ｃ语言编写的源程序中的每个单词符号，并以记号的形式输出每个单词符号。 (2)可以识别并读取源程序中的注释。 (3)可以统计源程序中的语句行数、单词个数和字符个数，其中标点和空格不计算为单词，并输出统计结果。 (4)检查源程序存在的错误，并可以报告错误所在的行列位置。 (5)发现源程序中存在错误后，进行适当的恢复，使词法分析可以继续进行，通过一次词法分析处理，可以检查并报告源程序中存在的所有错误。实现要求：采用C/C++作为实现语言，手工编写词法分析程序。 -Compiler theory lexical analysis program. Title: lexical analysis program design and implementation of experimental content: the design and realization of C language lexical analyzer requirements are as follows. (1) can identify each word in the C language source code symbols, and outputs of each word to the mark in the form of symbols. (2) can identify and read the comments in the source code. (3) Statistical statement the number of rows in the source code, the number of words and the number of characters, including punctuation and spaces does not count as a word, and output of the statistical results. (4) Check the source error, and can report the error where the ranks of the position. (5) found that there is an error in the source program, proper recovery, lexical analysis can proceed through a lexical analysis processing, you can check and report all errors in the source. Requirements: adopt the C/C++ as the implementation language, hand-written lexical analyzer.

[Other] lex DL : 0: 设计并实现 C 语言的词法分析程序，要求如下。 (1) 可以识别出用C语言编写的源程序中的每个单词符号，并以记号的形式输出每个单词符号。 (2) 可以识别并读取源程序中的注释。 (3) 可以统计源程序中的语句行数、单词个数和字符个数，其中标点和空格不计算为单词，并输出统计结果。 (4) 检查源程序中存在的非法字符错误，并可以报告错误所在的行列位置。 (5) 发现源程序中存在错误后，进行适当的恢复，使词法分析可以继续进行，通过一次词法分析处理，可以检查并报告源程序中存在的所有词法拼写错误。-Design and implementation of C language lexical analysis procedures, requirements are as follows. (1) can be identified using the C language source code for each word symbols, and mark each word in the form of output symbols. (2) can recognize and read the comments in the source program. (3) you can count the number of rows in the source program statements, the number of words and number of characters, including punctuation and spaces are not counted as words, and output statistics. (4) Check the source of the illegal character errors exist, and can report the error location where the ranks. (5) found that there are errors in the source after proper recovery, so that lexical analysis can proceed through a lexical analysis process, you can check and report the source of all existing lexical spelling errors.

[Other] scanner DL : 0: 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
