这个是编译原理的词法分析的实验报告！很不错，希望大家支持！-this principle is to compile the lexical analysis of the experimental report! Quite well, and hope that we support!

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.

用户输入一个文法，然后再输入，要被分析的字符串，自动进行语法分析，把每一不的分析过程都一一打印出来。直到分析成功或失败。-a user input grammar, and then imported to the string were analyzed automatically syntax analysis, the analysis of each process does not have to print out on January 1. Until the analysis of success or failure.

一个程序，用于判定给定的文法是否为LL（1）文法。 实现了：1．文法的机内表示；2. FIRST集和FOLLOW集的计算； 3. LL（1）预测分析表的构造。-a procedure for the determination of grammar to whether LL (1) grammar. Realized : 1. Grammar said the machines; 2. FIRST FOLLOW sets and set computing; 3. LL (1) Forecast and Analysis table structure.

有用，非常得有用。- Useful, extremely usefully.
