LL(1)文法使用的是确定的自顶向下的分析技术。LL(1)的含义是:第一个L表明自顶向下分析是从左向右扫描输入串,第2个L表明分析过程中将使用最左推导,1表明只需向右看一个符号便可决定如何推导,即选择哪个产生式(规则)进行推导。-LL (1) grammar using a set top-down analysis techniques. LL (1) the meaning is: the first one L shows a top-down analysis is a scan input string from left to right, the first two L shows the analysis process will be the most left-derivation, one that will be just right to see a sign can decide how to derive, choose what Production (rules) for derivation. LL (1) grammar, followed by calculation of the discriminant needs FIRST sets, FOLLOW sets and SELLECT set, and then determine whether to LL (1) grammar, the last sentence further analysis.

前些天写了个小语言的词法分析程序,因为前些天在VC知识库看到一个pascal词法分析的程序,觉得写得挺复杂的。其实词法分析程序的原理都是一样的,所以我想只要搞明白了简单的词法分析程序,再写复杂的就不难了,无非是多加几个关键字,多写几个条件判断语句而已。词法分析是编译程序的基础,也是最简单的。好,现在让我们看程序吧。 先让我们看看这个小语言的文法吧-few days ago wrote a small language lexical analysis procedures, because the other day in the knowledge base to see a VC pascal lexical analysis procedures, find that quite complex. In fact, lexical analysis procedure is the same principle, I think if you understood a simple lexical analysis procedure to write complex it is not difficult, is nothing but add a few keywords and writing several conditions judgment statement it. Lexical analysis is the basis of compilers, as well as the most simple. Well, now let us look at the procedures it. Let us look at this small language grammar it

该系统是本人课程设计作业,因为时间关系,只用了两天多的时间编成。所以有很多地方没有得到增强。版本为1.0。现作以下升级。 增加NEW,OPEN版本。 提高输入容错。判断输入的对错。 时间关系,搜索功能为线性搜索,现增强如下:f_search:费氏查找法;btree:二叉树查找法;l_search:线性查找法; r_search:递归折半查找法;zcsear:杂凑碰撞查找法;o_sear:插补查找加强法; 排序是冒泡法,现增强为:heaps:累堆排序;binary:二叉树排序;xieer:谢耳排序;sinsert:插入排序;quicks:快速排序;select:选择排序法; 有时间不仿试试。-f_search: Find Act Fernandez btree: binary tree search method l_search: linear search method r_search: Recursive half Find Law zcsear: Find a hash collision law o_sear: interpolation search Enhancement Act sort is bubbling method are enhanced for: heaps: HEAPSORT tired binary: binary tree sort xieer: Xie ears sort sinsert: Insertion Sort quicks: quick sort select: Select Sort Method
