NEC 78F1166做的线路检测仪来测量产品的线路是否有问题-NEC 78F1166 make the line detector to measure the product line if there are problems

一个由LEX编写的C-词法分析程序。为锻炼使用者能力，未加载LEX已编译的代码。建立时最好建立控制台程序。-LEX written by a C-lexical analysis program. The user the ability to exercise without load LEX compiled code. Is best to establish procedures for the establishment of the console.

一个识别c语言关键字和大小写转换的程序-an identification and case-insensitive language keyword conversion process

c实现的四元式，模拟编译原理来实现，程序本身没什么难度，不过写这种程序能进一步加深对编译原理的理解！-c 4 yuan to achieve the style, analog compiler principles to achieve, the process itself little more difficult, but to write such a procedure would further deepen the understanding of compiler theory!

词法分析器 对输入的程序进行分析，将关键字，保留字与系统标识符分开，并对其属性进行说明。 建立数组，将单词读入，对单词的ASCII码进行判断，将在ASCII码值在一定区间进行区分（使用if语句来判断），分开来后，对其所在ASCII值区间的不同，给予以不同的属性(比如：系统保留字…），词法分析器完成后要能识别+,-,=等字符。-lexical analyzer on the importation procedures for analysis, keyword, the word reservation system with separate identifier, and a description of their attributes. The establishment of an array, you read the word, the right word ASCII judgment, in ASCII value in a certain area and distinguish between (use to determine if statements), separately, its value lies ASCII range of different, to give a different properties (such as : system retain the word ...), after the completion of a lexical analyzer to identify,-, =, etc. characters.

This is a java virtual machine implement in c

编译并且测试成功的虚拟机- Translates and tests successfully hypothesized machine

在CPLD内实现声调和时间的控制，在LATTICE的ISPLEVER6.1下编译通过。可以修改定时时间进行声调的修改-In the CPLD to achieve control of tone and time, in LATTICE under the ISPLEVER6.1 compiled through. Can be modified from time to time time to tone changes

简单的c0编译器，能够正确地将源码编译成功，并且生成四元试-C0 simple compiler, able to correctly compile the source code successfully, and generated four test
