Description: LR分析器设计
给定说明语句的拓广文法G[S ]如下：
(0) S ->S (1) S->v I:T (2) I->I,i (3) I->i (4) T->r
其中v代表终结符var,r代表real。
其识别规范句型活前缀的DFA及LR(0)分析表如下:
输入
状态 ACTION表 GOTO表
v i , : r # S I T
0 S2 1
1 acc
2 S4 3
3 S6 S5
4 r3 r3 r3 r3 r3 r3
5 S9 8
6 S7
7 r2 r2 r2 r2 r2 r2
8 r1 r1 r1 r1 r1 r1
9 r4 r4 r4 r4 r4 r4
编程实现此文法的LR分析器，并设输入的文法的句子为：
var i , i , i : real
给出输出结果
-LR parser design
Given that statement, The Extension of the grammar G [S ] as follows:
(0) S -> S (1) S-> v I: T (2) I-> I, i (3) I-> i (4) T-> r
One representative of terminator v var, r representative of real.
Living patterns of its identification Specification prefix DFA and LR (0) analysis as follows:
Input
GOTO table table status ACTION
v i,: r# S I T
0 S2 1
1 acc
2 S4 3

7 r2 r2 r2 r2 r2 r2
8 r1 r1 r1 r1 r1 r1
9 r4 r4 r4 r4 r4 r4
Programming LR parser article law, and set the input sentence is the grammar:
var i, i, i: real
Given output

Description: 实验三 LR分析法的实现
一、实验目的
实现一个关于表达式的LR语法分析程序，识别用户输入的包含变量与整数的混合算术表达式（不包含减法与除法运算）。
-二、实验主要内容
1、文法如下：
0) S E
1) E E+E
2) E E*E
3) E (E)
4) E i
2、对应的LR分析表如下：
状态 ACTION GOTO
+ * ( ) i # E
0 S2 S3 1
1 S4 S5 acc
2 S2 S3 6
3 r4 r4 r4 r4
4 S2 S3 7
5 S2 S3 8
6 S4 S5 S9
7 r1 S5 r1 r1
8 r2 r2 r2 r2
9 r3 r3 r3 r3
3、编程运用上述LR分析表，识别从键盘输入的算术表达式。
4、对于语法错误，要指出错误具体信息。

Description: 类C语言编译器，基本上实现了主要功能的C语言语法，词法分析使用状态转移，语法使用LR（1）方法，自动生成ACTION和GOTO转移表。自顶向下的语法制导翻译，可以生成各种类型的表达式（包括布尔，算术，逻辑等等），循环中的while，选择中的if else 和if等，功能比较强大-Class C language compiler, basically realized the C language syntax, lexical analysis of the main features of the use of state transition, syntax LR (1) method to automatically generate ACTION and GOTO jump table. Top-down syntax-directed translation, you can generate various types of expressions (including Boolean, arithmetic, logic, etc.), the loop while, selection if else and if so on, more powerful
