用C++编写的算符优先关系分析程序.主要应用FIRSTVT和LASTVT集来构造算符优先关系表。-Prepared using C++ operator precedence relations of the analytical procedures. LASTVT main FIRSTVT and priorities set to construct the relationship between the table operator.

设计一个给定文法和对应的FIRSTVT和LASTVT集，能依据依据文法和FIRSTVT和LASTVT生成算符优先分析表。 动态模拟算法的基本功能是： 1. 输入一个给定文法，及FIRSTVT和LASTVT集； 2．输出算符优先分析表生成算法； 3．输出算法优先分析表构造过程的过程； -The design of a given grammar and the corresponding set FIRSTVT and LASTVT can based on the basis

算符优先算法，输入文法数和文法，自动分析生成firstVT和lastVT，并显示表，输入字符串，判断该字符串是否符合要求-Operator priority algorithm, the number of input grammar and the grammar, generate automatic analysis firstVT and lastVT, and display the table, enter the string to determine whether it mee
