Description: 编译原理：词法分析器(C++实现)
将PASCAL的源程序，即相应字符流转换成内部表示，并对标识符填写相应的符号表供编译程序以后各阶段使用，输出的单词符号格式为二元组（单词种别，单词在标识符表中的地址），标识符表格式有“序号”和“标识符本身的值”两项。-compiler : lexical analyzer (C achieved) will PASCAL source, that is, replaced by the corresponding characters in the internal circulation, also fill in the corresponding identifier of the symbol table compiler for the subsequent stages, Word output format for binary symbols (words of other species, the identifier word in the address table) Table format identifier "serial number" and the "value of the identifier" 2.

Description: C语言 词法分析器。
(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,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.-C language lexical analyzer. (1) can be identified with the C source program written in symbols for each word, and to mark each word in the form of output symbols. (2) to identify and read the comments in the source program. (3) can be statistical source of the statement line number, word number and the number of characters, including punctuation and spaces are not counted as words, the output results. (4) Check the source in the presence of illegal character errors, and the ranks of the errors can be reported position. (5) found that there is an error source, the proper recovery, so that lexical analysis can proceed, through a lexical analysis and processing, you can check and report on all of the lexical source spelling errors.

Description: Parses forwards and backwards.
-Scans forwards and backwards.
-Get the delimiter that was found.
-Get the offset at where the token was started.
-Get the current offset of the parser.
-Add any number of delimiters.
-Support for delimiter lists. Instead of removing all delimiters and adding one by one, just set the delimiter list. Can be used for easier parsing out of comments.
-Unicode/Ansi Support
Included is also 5 tests showing all the functions in action. Sample text is mostly a snippet of C++ source code except for one test. Shows the ease of use for parsing with support multiple delimiters. Platform: |

Description: 词法分析（英语：lexical analysis）是计算机科学中将字符序列转换为单词（Token）序列的过程。进行词法分析的程序或者函数叫作词法分析器（Lexical analyzer，简称Lexer），也叫扫描器（Scanner）。(Lexical analysis is the process of converting character sequence into token sequence in computer science. The program or function for lexical analysis is called lexer or scanner.) Platform: |
