这是一个迭代法实现的C代码。本算法采用的是SOR迭代法。-This is an iterative method to achieve the C code. This algorithm is used SOR iteration.

本课程设计的题目为“FirstVT集和LastVT集生成算法模拟”，它是算符优先分析算法中判断三种优先关系的关键。算符优先分析算法是自底向上分析方法的一种。所谓自底向上分析，也称移近—规约分析，粗略地说它的实现思想是对输入符号串自左向右进行扫描，并将输入符逐个移入一个后进先出的栈中，边移进边分析，一旦栈顶符号串形成某个句型的句柄或可规约串，就用该产生式的左部非终结符代替相应右部的文法符号串，这称为一部规约。重复这一过程直到规约到栈中只剩文法的开始符号则为分析成功，也就确认输入串是该文法的句子。而算符优先分析算法的基本思想只是规定算符之间的优先关系，也就是只考虑终结符之间的优先关系。 本课程设计的要求就是根据文法构造FirstVT集和LastVT集，为以后扩充建造算符优先分析表打好基础。
