C语言实现的SIMPLE语言词法分析器，并用JAVA实现界面。

算术表达式词法和语法分析程序,递归下降法,四元式-Arithmetic expression lexical and syntax analysis, recursive descent method, type Quaternion

有限自动机的运行，利用状态表和有限自动机的运行原理，识别一个输入串是否为一个有效的无符号定点实数。-of the operation, the use of tables and limited state of the automatic machine operation principle, to identify whether an input string as a symbol of effective non-sentinel real.

A simple tic tac toe program using prolog

java写的词法分析器，写得不好别怪我-java writes the morphology analyzer, writes is not good do not blame me

C programm for frequency distribution.

这是一个完整的词法分析器，用Ｃ＋＋编写，并有测试文件-This is a complete lexical analyzer, C++, and test document

c语言编译器，面向windows的，不用注册即可使用-c language compiler, facing the windows, and do not have to register to use

解法:对原文法消除左递归,根据消除左递归后的等价文法建立语法树,而后对此语法树 进行后根遍历,即可得到后缀式.- Solution: Eliminates the left recursion to the original grammar, after equal in value grammar establishment grammar tree which eliminates the left recursion, after but the grammar tree carries on the root to spread the calendar regarding this, after then obtains decorates the type
