[ELanguage] while DL : 0: 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.

[ELanguage] Simple_Language_Lexer DL : 0: 这是一个使用了LEX所编写的Simple语言的词法分析器。Simple语言的定义说明请看附件。这个LEX的源代码可以通过Parser Generator 2来转化成为h文件跟cpp文件。由于编译这两个文件需要使用到Parser Generator 2的C++库，所以就只上传了LEX的源代码，谁感兴趣的可以自己通过Parser Generator 2来转化。至于UNIX下面的LEX工具如果想要转化的话需要修改其主程序，另外需要将LEX源代码之中有关C++语言的表达形式修改成为相应的C语言的表现形式才行之。总体这样子。-This is one written by using the LEX lexical analyzer Simple language. Simple definition of the language description see annex. The LEX source code can be transformed into Parser Generator 2 to h file with the cpp file. As the compilation of these two files need to use the Parser Generator 2 in C++ library, so we just uploaded the source code for LEX, who may be of interest to themselves through Parser Generator 2 to transform. As for the UNIX tools LEX below if you want converted, then need to modify its main program, another will need to LEX source code into the C++ language, forms of expression changes as the corresponding C-language expressions of Caixing. Overall like this.

[ELanguage] Lexical_Analysis DL : 0: 设计并实现C语言词法分析程序。要求如下：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。可以识别并读取源程序中的注释。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。检查源程序中存在的错误，并可以报告错误所在的行列位置。发现源程序中存在的错误后，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，可检查并报告源程序中存在的所有错误。采用C/C++作为实现语言，手工编写此法分析程序。-Design and implementation of C language lexical analysis program. Requirements are as follows: Can identify the source with the C language symbol for each word, and to mark each word in the form of output symbols. Can identify and read the source of the comment. Statistical source of the statement could be the number of lines, words, numbers and character numbers, punctuation and spaces which are not counted as words, and output results. Check the source of errors, and can report the errors in the ranks of the position. Found that errors exist in the source program after the appropriate recovery, so that lexical analysis can proceed, through a lexical analysis, may inspect and report all errors that exist in the source program. Using C/C++ as implementation language, hand-written procedure for this method.
