SIP软件开发记录 由于通信网的封闭性，网络结构的复杂性，通信设备的多样性，使得通信软件难以在一个统一的平台（包括硬件平台和操作系统平台）下运行，所以迄今为止，通信行业的开源项目仍屈指可数。 　 　下面，我们把通信类的软件简单的进行一下划分-SIP software development record as a closed network, network structure of the complex nature of the diversity of communications equipment, making it difficult to communication software in a unified platform (including the hardware platform and operating system platform) running, so far, the telecommunications industry is still a few open-source projects . Now, we kind of communication software for about a simple division

是关于一个词法分析器的一个程序-Is about a morphology analyzer procedure

目的：通过编写简单的YACC程序熟悉YACC词法分析工具的基本用法，及词法分析器的设计思路。编写包括赋值语句、if语句以及含有加合乘运算的表达式等语法结构的pascal子集语言的语法分析器。 功能：程序由两个模块LEX和YACC构成，YACC使用LEX分析后的正规单词输出流-Objective : to prepare a simple procedure with YACC YACC lexical analysis of the basic tools to use, and the lexical analyzer designs. Preparation including assignment if statements containing Addition and multiplication of expressions such as grammatical structure of the pascal subset of the language syntax analyzer. Function : procedures by the two modules constitute LEX and YACC, YACC LEX analysis using the formal word output streams
