输入：输入是一个文本文件，里面的内容是符合某个语言语法、词法要求的源代码（输入文件为C++或者Java源程序，词语、语法定义参考C++、Java即可；C++、Java大家只需要选择一种自己熟悉的语言就可以），例如“position = initial + rate * 60 ”；

输出：设计并实现对输入文件的处理（禁用正则表达式），以获得如下输出，输出是一个文本文件，对前面例子，里面内容是：

(标识符，position)

(赋值运算符，=)

(标识符，initial)

(加法运算符，+)

(标识符，rate)

(乘法运算符，*)

(整数，60)

(分隔符， )-Input: The input is a text file, which is in line with the contents of a language grammar, syntax required source (input file as C++ or Java source code, words, syntax definition reference C++, Java can　C++, Java we only need choose a familiar language can be), for example,　position = initial+ rate* 60　

Output: design and realization of the input file processing (disable regular expressions) to obtain the following output, the output is a text file, for the previous example, which reads:

(Identifier, position)

(The assignment operator, =)

(Identifier, initial)

(Addition operator,+)

(Identifier, rate)

(Multiplication operator,*)

(Integer, 60)

(Separator, )
