现将本人搜集常用的程序设计语言的词法和形式文法提供给大家。其中，词法是按LEX格式编辑，形式文法是按YACC格式书写，大家可直接用LEX和YACC工具编译生成各类程序设计语言的分析器。-commonly used programming language syntax and grammar forms to the public. Among them, morphology is based on LEX format editing, grammar form is written by YACC format, we can use the LEX and YACC tools various compiler generation programming language analyzer.

c语言编译器源代码，small c for dos源代码，对学习c语言本质很有好处。-c language compiler source code, small c for dos source code, the nature of learning c language is very good.

这是一份实验报告，目的是掌握YACC的使用方法，了解YACC处理二义性的方法。 用YACC等工具生成如下文法表示的表达式对应的计算器 exp->exp + exp | exp - exp| exp * exp |exp / exp |exp ^ exp | - exp |(exp) |NUM 对于输入的表达式，能输出结果。比如: 3 +(4 *5)结果应为23 当出现错误时可以进行错误处理。 -This is a test report, the purpose is to master the use YACC to learn YACC handling of the ambiguity approach. Using tools such as YACC grammar that generates the following expression for the corresponding calculator exp-> exp+ exp | exp- exp | exp* exp | exp/exp | exp ^ exp |- exp | (exp) | NUM expression for the input type, can be output. For example: 3+ (4* 5) the result should be 23 when the error can be error-handling.
