这是一个使用了LEX所编写的Simple语言的词法分析器。Simple语言的定义说明请看附件。这个LEX的源代码可以通过Parser Generator 2来转化成为h文件跟cpp文件。由于编译这两个文件需要使用到Parser Generator 2的C++库，所以就只上传了LEX的源代码，谁感兴趣的可以自己通过Parser Generator 2来转化。至于UNIX下面的LEX工具如果想要转化的话需要修改其主程序，另外需要将LEX源代码之中有关C++语言的表达形式修改成为相应的C语言的表现形式才行之。总体这样子。-This is one written by using the LEX lexical analyzer Simple language. Simple definition of the language descr iption see annex. The LEX source code can be transformed into Parser Generator 2 to h file with the cpp file. As the compilation of these two files need to use the Parser Generator 2 in C++ library, so we just uploaded the source code for LEX, who may be of interest to themselves through Parser Generator 2 to transform. As for the UNIX tools LEX below if you want converted, then need to modify its main program, another will need to LEX source code into the C++ language, forms of expression changes as the corresponding C-language expressions of Caixing. Overall like this.
