Question

我怎样才能使条件变得更好，因为它具有同样满足大于零的条件。以下是代码：

a = 10
b = 5
c = 2

if a > 0 || b > 0 || c > 0
  puts "greater that zero"
else
  puts "it is zero or less than zero"
end

Answer 1

我可能会这样做

if [a, b, c].any? { |x| x > 0 }
  puts "greater that zero"
else
  puts "it is zero or less than zero"
end

Answer 2

怎么样：

if [a, b, c].max > 0
  puts "greater that zero"
else
  puts "it is zero or less than zero"
end

Answer 3

我喜欢使用三元运算符来表示真或假的情况。

[a,b,c].any?(&:positive?) ? "greater that zero" : "it is zero or less than zero"
