本设计使用C语言实现了对简单方法描述的LL(1)文法的判定。该设计程序实现了:⑴分别求出每一产生式的右部的FIRST 集、每一个非终结符的FOLLOW集和每一产生式的SELECT集;⑵判定是否是LL(1)文法;⑶画出预测分析表;⑷对给定的符号串判定是否是文法中的句子,分析过程在屏幕上打印出来。 欢迎大家给程序提出富贵意见!

检测windows下rootkit对文件的隐藏。some usermode overwrites first few bytes of ZwQueryDirectoryFile and that trick will fail then :( So, you will probably need a small database of the correct indexes for all Windows versions

eForth is a small portable Forth design for a wide range of microprocessors. This is the first implementation for 8086. As machine dependency is consolidated into 31 code words, moving eForth to other CPU s will be much less of a chore comparing to other Forth models.

* Function: * 1. Replace the first oldstr with newstr in srcstr * Arguments: * IN : * srcstr * oldstr * newstr * OUT : * srcstr * Return: * 1. If find and replace one oldstr with newstr in srcstr , return 1 * 2. If find no oldstr in srcstr , return 0 * 3. If error (malloc return NULL) return -1 * Notes: * 1. srcstr should be large size enough.

比如源程序sum ∶= first+count*10可生成四元式序列,如图1.7所示,其中ti(i=1,2,3)是编译程序生成的临时名字,用于存放运算结果的。 图1.7 id1:= id2 + id3 * 10的四元式序列
