功能: 自动绘制循环报表说明: 以可视化的方法自动绘制循环报表 可以任意指定对象属性, 属性支持原有表达式 支持SQL Select和外部数据源作用: 将繁琐的不可视代码调试转化为轻松愉快的可视化绘制 开发时间由以天为单位计算缩短为以分钟为单位-functions : automatic mapping cycle statements Note : Visualization of the automatic mapping cycle returns to be arbitrarily designated object properties, attributes to support the original expression of support for SQL Select and external data sources role : the cumbersome visual debugging code into a visual delight, drawing from a development time as days shorten terms for a minute as a unit

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。 -1 : a needs analysis. The process required the trees and the binary tree master the concept and principle, to use its principles and the concept of completion of the pilot. . 2. Problem description : If a logical expression for the changes in the yuan"s value for a true, as tautology; Instead, If the changes for the yuan"s value for a fake, then called the contradiction; However, the more the situation, neither tautology. is not a contradiction. Try to write a procedure for the adoption of a truth table judgment logical expression belong into that category. 3. Basic requiremen
