一个小巧而且实现很完整的JAVA虚拟机-achieve a compact but complete Java Virtual Machine

这个因为是我们老师让做的阶乘的代码，还算不错，希望给朋友门一点启发

语义分析器，将语义分析程序编制成子程序，在语法分析器分析出各语法单位后，分析其含义，并将可执行语句或表达式翻译为四元式输出，并将错误信息输出。-Semantic analyzer, semantic analysis program compiled subroutines, in the parser analyzes the syntax of the unit, analyze its meaning, and translated into an executable statement or expression quaternary-output, and error information output.

pascal编译器，可生成中间代码，简单实用-pascal compiler, can generate between code, simple and practical

convert MATHML to SVG

VC 6.0 下编译通过 disc 为辞典 expression 为输入的短语-it can complier in VC6.0,glossary is disc,inputting phrase is expression

一个读单词过程，从输入的源程序中，识别出各个具有独立意义的单词，即基本保留字、标识符、常数、运算符、分隔符五大类。并依次输出各个单词的内部编码及单词符号自身值。（-read a word process, from the import of the source to identify all the independent significance of the word, that is to retain the basic character identifier, constant, Operators, separated top-five. Output and followed all the internal code words and symbols own words value. (

自己做的一个求集合的小程序，实现十分简单- Own do the script which asks to gather, the realization is extremely simple

解法:对原文法消除左递归,根据消除左递归后的等价文法建立语法树,而后对此语法树 进行后根遍历,即可得到后缀式.- Solution: Eliminates the left recursion to the original grammar, after equal in value grammar establishment grammar tree which eliminates the left recursion, after but the grammar tree carries on the root to spread the calendar regarding this, after then obtains decorates the type
