1、给出各单词符号的类别编码。 2、词法分析程序应能发现输入串中的错误。 3、词法分析作为单独一遍编写，词法分析结果为二元式序列组成的中间文件。 4、设计两个测试用例（尽可能完备），并给出测试结果。 -1, given the various types of code word symbols. 2, lexical analysis procedure should be able to detect errors in the input strings. 3, again as a separate lexical analysis prepared for morphological analysis of binary sequence consisting of between documents. 4, the design of the two test cases (as far as possible, complete), and gives test results.
