C_minus BNF language syntax definition of procedures from the list of statement...
C_minus语言的BNF语法定义 程序由声明的列表(或序列)组成,声明可以是函数或变量声明,顺序是任意的。至少必须有一个声明。接下来是语义限制(这些在C中不会出现)。所有的变量和函数在使用前必须声明(这避免了向后backpatching引用)。程序中最后的声明必须是一个函数声明,名字为main。注意,C-缺乏原型,因此声明和定义之间没有区别(像C一样)。-C_minus BNF language syntax definition of procedures from the list of statement (or sequence), with a statement can be variable or function statement, the order is arbitrary. There must be at least one statement. Next is the semantic constraints (these will not arise C). All the variables and functions to be used in the statement (which avoids the use Backpatching backwards). Procedures must be the last statement is a function declaration, the name of the main. Attention C- lack of a prototype, and the definition of a statement is no difference between (the same as C).

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)文法的判别需要依次计算FIRST集、FOLLOW集和SELLECT集,然后判断是否为LL(1)文法,最后再进行句子分析。
-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.
