我有4个阵列.
["one","two","three"] ["1","2","3" ["un","deux","trois"] ["ichi","ni","san"]
是否可以在各自的数组中连接每个元素？
所以我最终会得到像单行一样的字符串
"one,1,un,ichi"\n "two,2,deux,ni"\n
等等…
是否可以在一个循环中执行此操作？
for i in (1..array1.count) puts array1[i] + "," + array2[i] + "," + array3[i] + "," + array4[i] end
当可能存在不可预测的阵列数量时会发生什么？它们各自的大小不一样？
解决方法
好吧,如果你知道他们都是相同的长度：
(0...array1.length).each{|i|puts array1[i] + "," + array4[i]}
编辑：以下代码有效
array1 = ["one","three"]
array2 = ["1","3"]
array3 = ["un","trois"]
array4 = ["ichi","san"]
(0...array1.length).each{|i| puts array1[i] + "," + array4[i]}
编辑2：如果您不知道将有多少阵列会发生什么？
我建议制作一个数组数组;数组列表.创建一个数组数组(本质上是一个2D数组,但不能像一个数组一样索引),并使用它为arrayList中的每个数组逐个打印每一行.
此代码有效：
array1 = ["one","san"]
arrayList = []
arrayList.push(array1,array2,array3,array4)
p arrayList
(0...array1.length).each{|i|
(0...arrayList.length).each{|j|
print arrayList[j][i] + ","
}
print "\n"
}
