用C语言采用模拟DFA算法编写一个扫描器（词法分析器）用来识别：
由任意个a或b开始后接aa再自加或自减1的字符串，即正规式r=(a|b)*aa(+|-)1描述的语言L（r）。
Simulated DFA algorithm in C language to write a scanner (lexical analyzer) is used to identify: followed by any one of a or b aa longer self plus or decrement a string, the regular expression r = (a | b )* aa (+ |-) 1 described in the language L (r). (2012-10-17, Visual C++, 6KB, 下载13次)

此为广工09级编译原理课程设计，与往届是有区别的
1． 课内实验（考试前交报告）

（1）增加单词：保留字 ELSE，FOR，STEP，RETURN
运算符 +=，-=，++，--，&，|，!
（2）修改单词：不等号# 改为 <>
（3）增加条件语句的ELSE子句，要求：写出相关文法，语法图，语义规则。
2． 课程设计
基本内容（成绩范围：“中”、“及格”或“不及格”）
（1）扩充赋值运算：+= 和 -=
（2）扩充语句（Pascal的FOR语句）:
①FOR <变量>:=<表达式> STEP <表达式> DO <语句>
②FOR <变量>:=<表达式> STEP <表达式> DO <语句>
其中，语句①的循环变量的步长为1，
语句②的循环变量的步长为-1。
（3）增加运算：++ 和 --。

A.Curricular experiment (before the examination of reports submitted)
Modify the expansion of the PL/0 to make the following:
(1) increasing word: reserved word ELSE, FOR, STEP, the RETURN
Operator+ =,- =,++,-, &, |,!
(2) modify the words: inequality# changed <>
(3) increase in the conditional statement ELSE clause: Write the related grammar, syntax diagrams, semantic rules.
Two. Curriculum design
The basic content (score range: "", "pass" or "fail")
(1) expansion of the assignment operator:+ = and- =
(2) expansion of the statement (Pascal FOR statement):
① The the FOR <variable>: = <expression> the STEP <expression> DO <statement>
② the FOR <variable>: = <expression> the STEP <expression> DO <statement>
Among them, the loop variable of the statement (1) step 1,
Statement ② loop variable step size to-1.
(3) increase the operator:++ and-.

在VC下打开LRTrans1.dsp，阅读工程LRTrans1，LRTrans1为一个加、乘（适当扩充可为四则）运算表达式的SLR语法分析器，规定其文法如下：

(1) E->E+E
(2) E->E*E
(3) E->(E)
(4) E->i
经分析其SLR(1)分析表如下（分析表按“操作符运算优先级和运算符的结合率”方法解决冲突——*优先集高于+，*和+的结合率均为左结合）
