Description: 东南大学 课程设计 lex部分
说 明
**本次实验在Visual C++6.0环境下开发**
主要有以下文件：
1 词法分析器 lex.cpp
2 头文件 lex.h
3 测试文件 lex.l.txt
lex工具的使用方法
编译运行 lex.cpp/lex.h,这样就将lex.l.txt转换成Cpp语言程序yylex.cpp
然后使用VC++6.0将lexyy.cpp编译成可执行程序, 这样就识别出了lex.l.txt中的正规表达式
打印出的字幕代表了识别出相应正规表达式时的动作。-Southeast University curriculum design lex** Note part of this experiment in Visual C 6.0 open environment** fat mainly in the following documents : a lexical analyzer lex.cpp two documents lex.h three test documents for lex.l.txt lex with the use of compiler running lex.cpp/lex.h. This will be converted into tracing lex.l.txt Language Program yylex.cpp then use the VC 6. 0 to lexyy.cpp compiled executable. This lex.l.txt identified by the formal expression of subtitles printed out on behalf of the formal identification of the corresponding table TAT-time action. Platform: |

Description: Lex 和Yacc 简明教程
本书将教会你如何使用lex 和yacc 构造一个编译器。 lex 和yacc 是两个用来生成词汇分析器和剖析器的工具。
导言部分描写了构建编译器所需的基本部分，以及lex 和yacc 之间的互动关系。后面两章更加详细的描写了lex 和 yacc。构建了一个经典的计算器程序。这个计算器支持常用
的算术符号和控制结构，例如实现了像ifelse和while 这样的控制结构。经过小小的修改，就把这个计算器转换成一个可以运行在基于栈的计算机上的编译器。-Lex and Yacc tutorial concise book will teach you how to use lex and yacc to construct a compiler. lex and yacc are used to generate lexical analyzer and parser tools. Introductory section describes the compiler to build the basic parts, as well as lex and yacc interaction between. Behind the two chapters of a more detailed description of the lex and yacc. Construction of a classic calculator program. The calculator supports the common arithmetic symbols and control structure, for example, realize like ifelse and while such a control structure. After small modifications, so the calculator can run into a stack-based computer compiler. Platform: |

Description: 否符合while语句的文法，或者能不能通过文法的开始符号推导出该语句。
(2) 该程序应该包括词法分析器，能对输入的语句进行词法分析，然后再对输出结果。词法分析器应能识别关键字，标示符，常量，操作符等。
(3) 该程序的语法分析器能对输入的语法进行分析，判断输入语句能否满足while循环语句的文法。通过简单优先的方法对语句进行分析，看能否能归约到文法的开始符号。
(4) 该程序的语义分析器就是对分析结果进行输出，要求输出结果是三地址形式的。-Compliance with the statement while the grammar, or to the beginning of grammar symbols can not be derived from the statement. (2) The program should include the lexical analyzer, the statement can be carried out input lexical analysis, and then output the results. Lexical analyzer should be able to identify the keywords, identifiers, constants, operators and so on. (3) parser of the program can analyze the syntax of input to determine whether the input statement to meet the loop while the grammar. Priorities through a simple statement of the method of analysis to see whether it can reduce to the beginning of grammar symbols. (4) the program analyzer is the semantic analysis of the results of the output requirements of the output is three-address form. Platform: |
