truE or not?

与或非and or Not三个逻辑运算符的优先级应该是Not > And > Or 所以: True or False and True Or False 首先应该计算And,上式就相当于 = True Or (False And True) Or False '先是And运算 = True Or False OR False '然后是第一个Or运算 = Tru...

not会和紧邻的接合,and优先于or, 所以处理顺序应该是 not not True = True Flase and not True = False and False = False 最后是True or False = True

pascal的运算符优先级为 not > and > or 所以not true of true and false = (not true) or (true and false) = false

You consigned XiaoYin to tell me that you already had a boyfriend,I do care that,what ever it is true or not,you will have my sincerely wishes!...

a b !(a||b) (!a)||(!b) 0 0 1 1 0 1 0 1 1 0 0 1 1 1 0 0 直观

(a>0 or b>0) and not (a>0 and b>0) 或者 (a>0 or b>0) and a*b0 or b>0) and a*b

1=3计算结果为false, not false 即为true 5=5计算结果为true,not true 即为false, true and false 即为false true or false 即为true 所以最终结果为true

not "a">"b" and 63 =not false and false or true关系运算优先于逻辑运算 =true and false or true非运算优先 =false or true与运算优先 =true

与或非and or Not三个逻辑运算符的优先级应该是Not > And > Or 所以: True or False and True Or False 首先应该计算And,上式就相当于 = True Or (False And True) Or False '先是And运算 = True Or False OR False '然后是第一个Or运算 = Tru...

对,应为先执行and操作,而3>5是错误的,所以3>5and‘ABC’>'ABB'是false,然后执行not 1>2操作,这个是true,最后才执行or操作,也就是false or true,所以最后结果是true
