Description: 简单的lex编程，详细见英文描述
Running the Lex program
1. Write the Lex specifications as described above in a file, say, prog1.l
2. On moon.cse.yzu.edu.tw, do the following:
flex prog1.l (Produces lex.yy.c as the output)
gcc lex.yy.c -lfl (Compile the C file and link with Lex library)
a.out (Run the executable, and type the input, followed by )
or, if the input is in a file, say, hw1.in, then do the following:
a.out < hw1.in-Write the LEX program as per the specifications below.
--------------------------------------------------------------------------------
Recognize Action
Arithmetic (+,-,*, /) Print the operator along with the line number
Relational (<, <=, >, >=, !=, ==) Print the operator along with the line number
Assignment (=) Print the operator along with the line number
Parenthesis (left and right ones) No action for now
Some set of Reserved Words (for, if, while, int, ...) Print the Reserved word along with the line number
Identifiers Insert into a table and keep track of the line number
Numbers Print the number (should handle integer and floating point) along with the line number
Keep explicit track of the current line number by recognizing "\n" as a separate token. Do not use the LEX line number variable.
At the end, print the number of distinct identifiers and the line numbers on which they occur.
Sample Input:
int i, n, sum
i =

Description: 词法分析器又称扫描器。词法分析是指将我们编写的文本代码流解析为一个一个的记号，分析得到的记号以供后续语法分析使用。词法分析器的工作是低级别的分析：将字符或者字符序列转化成记号。-Lexical analyzer, also known as scanners. Lexical analysis refers to the text of the code we write flow analysis for a token one, analyze the resulting syntax notation for subsequent analysis. Lexical analyzer' s job is low-level analysis: the character or sequence of characters converted into tokens.
