Binary operator "<=" can't be applied to operands of type Bool and Int

Question

if 1 <= A[i] <= 100 || 1 <= B[i] <= 100 

for the above line I get these two error. 1. Adjacent operators are in non-associative precedence group 'Comparision Precendence' 2. Binary operator "<=" can not be applied to type BOOL and Int.

Answer 1

try if (1 <= A[i] && A[i] <= 100) || (1 <= B[i] && B[i] <= 100)

Answer 2

Joe的回答和Leo的评论都有效。我的偏好是Leo的方法（使用1...100 ~= A[i]），但无论你的船是什么漂浮。

那就是说，让我解释为什么你所做的是给你一个错误。没有任何括号来分解它，它会评估从左到右。因此，如果第一次检查＆＃34;是1＆lt; = A [i]？＆＃34;，则会产生布尔答案。然后它试图询问＆＃34;是否为真＆lt; = 100？＆＃34;，这没有任何意义。
