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
