一个语法分析程序,C++写的,内含原码和exe文件. 开发工具:DEV

用mfc编的一个mini pascal compiler，有交互界面，方便用户操作，对于学编译原理以及正在研究mfc的同学来说，是相当不错的参考源码。-mfc series with a mini pascal compiler, interactive interface user-friendly operation, the compiler theory and science is studying mfc students, it is a fairly good reference source.

用栈实现算术运算- Operates with the stack realization arithmetic

这里以开始定义的PASCAL语言子集的源程序作为词法分析程序的输入数据。在词法分析中，自文 件头开始扫描源程序字符，一旦发现符合“单词”定义的源程序字符串时，将它翻译成固定长度的单 词内部表示，并查填适当的信息表。经过词法分析后，源程序字符串（源程序的外部表示）被翻译成 具有等长信息的单词串（源程序的内部表示），并产生两个表格：常数表和标识符表，它们分别包含 了源程序中的所有常数和所有标识符。- Here starts the PASCAL language subset source program which defines to take the lexical analyaer the data-in. In the lexical analysis, starts from the article article to scan the source program character, once discovered when conforms to "the word" the definition source program character string, translates it the fixed length the word interior to indicate, and looks up fills in the suitable information table. After the lexical analysis, the source program character string (source program exterior expression) is translated has and so on the long information the word string (source program internal expression), and produces two forms: The chart and the identifier table, they have separately contained in source program all constants and all identifiers.

吉林大学开发的类似于PASCAL语言的SNL编译器。-The SNL Compiler was designed by JiLin university.

我做的不好呀，请大家指教。- I do am not good, asks everybody to advise.

C++ C 词法分析器，编译原理， 运行时输入文件（input.txt）路径，文件内容为{}BEGIN FOR(I=0 I

用户输入一个文法，然后再输入，要被分析的字符串，自动进行语法分析，把每一不的分析过程都一一打印出来。直到分析成功或失败。-a user input grammar, and then imported to the string were analyzed automatically syntax analysis, the analysis of each process does not have to print out on January 1. Until the analysis of success or failure.
