Description: 使用递归子程序法设计一个语法分析程序，自顶向下分析方法.
1、使用递归下降分析算法分析表达式文法：
exp ::= exp addop term | term
addop ::= + | -
term ::= term mulop factor | factor
mulop ::= * | /
factor ::= (exp) | number
其中number可以是多位的十进制数字串（整数即可），因此这里还需要一个小的词法分析器来得到number的值。
2、该词法分析器以子程序形式出现，当需要进行词法分析时进行调用；
3、能够识别正确和错误的表达式；
4、在进行语法分析的过程中，计算输入表达式的值。

Description: 建立一个针对LL(1)文法编译器的自动生成器。要完成此编译器的生成器需对源文件进行两遍处理：第一遍词法分析，第二遍语法分析。语法分析程序用LL(1)语法分析方法。首先输入定义好的文法书写文件(所用的文法可以用LL(1)分析)，然后建立词法分析器，包括词法分析主程序、扫描器部分、关键字表等。经词法分析后分别计算所输入的文法的每个非终结符号的FIRST集合，每个非终结符号的FOLLOW集合，以及每个规则的SELECT集合，并判断任意一个非终结符号的任意两个规则的SELECT集的交集是不是都为空，如果是则输入文法符合LL(1)文法则可以进行分析。-For the establishment of a LL (1) grammar compiler automatic generator. To accomplish this compiler generator must deal with the source file twice: first pass lexical analysis, parsing the second time. Parser using LL (1) syntax analysis. First, write the input file defined grammar (grammar can be used in LL (1) analysis), and then create the lexical analyzer, including lexical analysis of the main program, scanner parts, keyword lists. The lexical analysis of the inputs were calculated for each non-terminal grammar symbol of the FIRST set of each non-terminal symbol FOLLOW set, and each set of the rule s SELECT and determine any non-terminal symbol of any two rules SELECT set intersection is not all empty, if it is in line with the input grammar LL (1) the text rule can be analyzed.

Description: （1）设计符号表
确定符号表的组织方式，一般应包括名字栏和信息栏，其中名字栏作为关键字。要考虑能够存储有关名字的信息，并可以高效地完成如下操作：
a.查找：根据给定的名字，在符号表中查找其信息。如果该名字在符号表中不存在，则将其加入到符号表中，否则返回指向该名字的指针；
b.删除：从符号表中删除给定名字的表项。
（2）设计词法分析器（也可以使用FLEX生成词法分析器）
设计各单词的状态转换图，并为不同的单词设计种别码。将词法分析器设计成供语法分析器调用的子程序。功能包括：
a. 能够拼出语言中的各个单词；
b. 将拼出的标识符填入符号表；
c. 返回（种别码， 属性值）。
（3）语法分析与中间代码产生器（也可以使用BISON生成语法分析程序）
要求用递归下降分析法、预测分析法或SLR分析法，实现对表达式、各种说明语句、控制语句进行语法分析。
若语法正确，则输出一棵语法树。
若语法错误，要求指出出错性质和出错位置（行号）。出错处理应设计成一个出错处理子程序。-(1) Design symbol table
Determine the symbol table of organization, the general should include the name bar and bar, where the name column as a keyword. To be considered capable of storing information about the name, and the following operations can be efficiently completed:
a find: Find its information according to the name given in the symbol table. If the name does not exist in the symbol table, then it is added to the symbol table, otherwise it returns a pointer to the name of the pointer
Delete: delete the given name from the symbol table entry.
(2) design of lexical analyzer (You can also use the FLEX generate the lexical analyzer)
The design of each word in the state transition diagram, and a word design for different kind as code. The lexical analyzer is designed for the parser calls the subroutine. Features include:
a. to spell out each word in the language
b. spell identifier fill in the symbol table
c. return (other code, attribute values).
