这是一个c程序，它是用来解决编译原理中的词法扫描程序，用来查添符号表。-c This is a program that is used to solve the compiler principles of lexical scanning procedures used to investigate Tim symbol table.

一个汇编语言与二进制代码的转换表，可以用编译器的设计。-a compilation of language and the binary code conversion table, you can use the compiler design.

编译原理：词法分析器(C++实现) 将PASCAL的源程序，即相应字符流转换成内部表示，并对标识符填写相应的符号表供编译程序以后各阶段使用，输出的单词符号格式为二元组（单词种别，单词在标识符表中的地址），标识符表格式有“序号”和“标识符本身的值”两项。-compiler : lexical analyzer (C achieved) will PASCAL source, that is, replaced by the corresponding characters in the int

这是一个VHDL（硬件描述语言）的编译器，更确切说是一个解释器，输入是VHDL语言，输出是经过提到后的符号表，也就是将VHDL中的重要变量比如输入输出变量和DFF等保存下来。-This is a VHDL (hardware descr iption language) compiler, more precise explanation is a device that is VHDL input, output was mentioned after the symbol table to
