如何用随机数填充数组? [英] How do I populate an array with random numbers?

问题描述

我试图用小于 9 的正整数填充一个由四个元素组成的数组.

I am trying to populate an array of four elements with positive integers that are less than 9.

这是我的代码:

generated_number=Array.new(4)#create empty array of size 4
generated_number.each do |random| #for each position in the array create a random number
  random=rand(10)
end
puts generated_number

我不明白我错过了什么.

I don't understand what I'm missing.

推荐答案

您可以将范围传递给 rand()

Array.new(4) { rand(1...9) }
