红宝石 - 整型转换为字符串 [英] Ruby - Convert Integer to String

问题描述

在Ruby中，试图打印出一个字符串中的单个元素是给我找麻烦。相反，看到每个人物的，我看到他们的ASCII值来代替：

In Ruby, trying to print out the individual elements of a String is giving me trouble. Instead of seeing each character, I'm seeing their ASCII values instead:

>> a = "0123"
=> "0123"
>> a[0]
=> 48

我在网上看了，但找不到任何办法让原来的0背出来。我有点新的Ruby，我知道它要的东西简单，但我似乎无法找到它。

I've looked online but can't find any way to get the original "0" back out of it. I'm a little new to Ruby to I know it has to be something simple but I just can't seem to find it.

推荐答案

或者你也可以整数转换为其字符值：

Or you can convert the integer to its character value:

a[0].chr
