Description: 一个逻辑表达式如果对于其变元的任一种取值都为真，则称为重言式；反之，如果对于其变元的任一种取值都为假，则称为矛盾式；然而，更多的情况下，既非重言式，也非矛盾式。试写一程序，通过真值表判断一个逻辑表达式属于那一类。-If a logical expression for the changes in the yuan's value for a true, as tautology; Conversely, if the changes for the yuan's value for a leave, they were called contradiction; However, the more the circumstances, neither tautology, but also of non-contradiction. Try to write a procedure for the adoption of a truth table judgment logic expressions belong into that category.

Description: 1.这个计算器可用在离散数学的数理逻辑中，纯属工具，随意传播，由java语言实现,解压即可运行，需要按照java环境。可以去这里下载运行环境：http://www.skycn.com/soft/3116.html 2.这个计算器可以计算逻辑表达式的值、对应的真值表、主析取范式、主合取范式。 3.输入表达式时可以在表达式栏中输入，也可用相应的按钮输入，变元只能是PQRST。由于等价连接词无法识别，所以用等号代替，这也是一个无奈的选择。 4.计算前请选择变元个数（默认为3元）并对变元赋值。变元个数最高为5，基本能满足日常的计算。 5.计算器有自动检查表达式是否正确的功能，如果判断功能有误，麻烦您告诉我您的表达式。-1. The calculator can be used in discrete mathematics mathematical logic and is purely tools, and they spread by java language, can extract operation, in accordance with the needs of java environment.

The calculator can or count the value of the expression logic, truth table corresponding to the main disjunctive, with the main SAT. 3. Importation of expression can be imported in the expression column, also available in the corresponding button input variables can only be PQRST. As conjunction equivalence can not be identified, and so synonymous substitution, this is a helpless choice. 4. Please choose before calculating variable number (default 3 million) as well as variable assignment. Arguments for the

Description: 一:需求分析
1．本程序需掌握树和二叉树的概念及工作原理，运用其原理及概念完成实验.。
2．问题描述：
一个逻辑表达式如果对于其变元的任一种取值都为真，则称为重言式；反之，如果对于其变元的任一种取值都为假，则称为矛盾式；然而，更多的情况下，既非重言式，也非矛盾式。试写一程序，通过真值表判断一个逻辑表达式属于那一类。
3．基本要求：
（1）逻辑表达式从终端输入，长度不超过一行。逻辑运算符包括“|”，“&”和“~”,
分别表示或、与和非，运算优先程度递增，但可以有括号改变，即括号内的运算优先。逻辑变元为大写字母。表达式中任何地方都可以含有多个空格符。
（2）若是重言式或矛盾式，可以只“显示True forever”或“False forever”，否则显示“Satisfactible”以及变量名序列，与用户交互。若用户对表达式中变元取一组值，程序就求出并显示逻辑表达式的值。

Description: 给出任意一个合式公式，我们应该怎样能够将它用C语句表示出来，并且能够计算它在各组真值指派下所应有的真值（或是逻辑运算的结果）。这有多种方法。下面我们给出一种较为简便的方法。上面我们已经给出了逻辑连结词的定义，根据这种定义方法，我们也可以把一个合式公式表示成为条件语句中的条件表达式，这样我们就可以得到该合式公式的逻辑运算结果了。
