Description: 我们设计的编译程序涉及到编译五个阶段中的三个，即词法分析器、语法分析器和中间代码生成器。编译程序的输出结果包括词法分析后的二元式序列、变量名表、状态栈分析过程显示及四元式序列程序，整个编译程序分为三部分：
(1) 词法分析部分
(2) 语法分析处理及四元式生成部分
(3) 输出显示部分

Description: 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。
对输入的程序语句进行分析。对每个非终结点定义单个函数，定义了它的后继节点。然后用一个构造来的函数，使定义的后继节点符合语法，否则报错。
-Analysis of the input process, the keywords, reserved words separate with the system identifier, and its properties are described. Create an array, read the word, the word of the ASCII code to judge the value in the ASCII code to distinguish a certain interval (using the if statement to determine), separately, the ASCII value of their range where different, giving different attributes (such as: the system of reserved words ...) After the lexical analyzer must be able to identify the+,-,= other characters. The input of the program statements for analysis. Defined for each single function of non-end point, defined its successor nodes. Then use a constructor to the function, so that subsequent nodes meet the definition of the syntax, or an error.

Description: 英文的句法分析器，重复下面的操作直到agenda为空并且输入中没有下一个词
若agenda为空，则把句子中下一个词的各种词法符号（词性）加入进来，
从agenda中取一个元素（设为C，位置为：p1-p2)
对下面形式的每个规则：
X->CX1...Xn，在activearcs中增加一条活动边：X->C o X1...Xn，位置为：p1-p2；
X->C，把X加入agenda，位置为：p1-p2
边扩展
将C加入到chart的位置p1-p2
对每个形式为：X->X1... o C...Xn的活动边，若它在p0-p1之间，则在activearcs中增加一条活动边：X->X1... C o...Xn，位置:p0-p2
对每个形式为： X->X1... Xn o C的活动边，若它在p0-p1之间，则在agenda中增加一个成分：X，位置为：p0-p2
