编译原理的一个小实例 YACC(Yet Another Compiler

编译原理实验中的yacc源码，是一个基于小类C语言的yacc程序，有助于学习yacc的编写。-principle experiment compiler generates the source code, is based on a subset of the C language yacc procedures, contribute to the preparation of learning yacc.

PL/0语言可以看成PASCAL语言的子集，它的编译程序是一个编译解释执行系统。PL/0的目标程序为假想栈式计算机的汇编语言，与具体计算机无关。 文件说明: PL.htm---PL/0语言基本原理 pl0.h---定义 PL0.cpp---实现 testPl0.cpp---使用方法举例 testPas.txt---一个LP/0语言源程序-PL/0 language may regard as the PASCAL language the subset, its compiler is a translation explanation execution system. The PL/0 target program for the imaginary stack type computer assembly language, has nothing to do with with the concrete computer. Document explanation that, PL.htm---PL/0 language basic principle pl0.h--- defines PL0.cpp--- to realize the testPl0.cpp--- application method to give an example testPas.txt--- a LP/0 language source program

一个小型的C++代码解释器，可以运行简单的C++代码。-A small C++ code interpreter, you can run a simple C++ code.

vb方面的编程，条形码编程。希望对大家有用。-vb aspects of programming, bar code programming.

PL0语言的编译器，好用VC++编写-PL0 language compiler, easy to use VC compiles

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

vigenre 是关于加密的java实现-vigenre java password

一个小计算器的实现(编译原理),用Lex和bison-Realize a small calculator (Principle compiler), with Lex and bison
