1、 输入串应是词法分析的输出二元式序列，即某算术表达式“实验项目一”的输出结果。输出为输入串是否为该文法定义的算术表达式的判断结果。 2、 递归下降分析程序应能发现输入串出错。 3、 设计两个测试用例（尽可能完备，正确和出错），并给出测试结果 -1, input strings should be the output of lexical analysis of binary sequence, that is, the arithmetic expression of a

编译原理实验之词法分析器，实现对输入的字符或语句进行词法分析器。-Compiler lexical analyzer of principle experiment, the realization of the input of characters or words for lexical analyzer.

这个程序是我们的大作业,里面有语法分析,词法分析,四原式等等,里面有具体内容和事例,看看就能明白-this procedure is our largest operation, which has syntax analysis, lexical analysis, the four original type and so on, there are specific details and examples, see we can understand

用ｃ语言实现的语法语义分析程序 实现了四元式得生成功能齐全-with language syntax semantic analysis of the program in four yuan-generation multifunctional

希望可以帮助同学在编译原理上有有更多的理解!- The hope may help the schoolmate in the translation principle has more understanding!
