编译原理 词法分析器 识别标识符，关键字，运算符，常量，界符包括出错处理...

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.

单独分离出来的C-手工词法分析器，需要自己建立一个工程来运行本程序。为《编译原理与实践》一书之后的实验题的代码。-Single isolated C-hand lexical analyzer, needs its own to establish a project to run this program. For " Compiler Construction Principles and Practice," a book after the experiment of the code.
