Print A to Z according to user's input: 1=A, 2=B, etc

I want to print characters from A to Z depending on the user's input. If the input is 1 then print A, if the input is 2 then print B, and so on.

I tried using a for loop as below, but wasn't able to achieve what I want.

for i in {a..z}
do
  echo $i
done

How can I use a loop or another approach to get the expected output?

0 + 0

bash

scripts

You can use an array:

#!/bin/bash
read i
a=(0 {A..Z})
echo ${a[$i]}

As arrays are zero-indexed, I simply put a 0 in front, so the array will be 0 A B C .... Otherwise you would get 0→A, 1→B, ...

0 + 0

See the `(...)` around the `{...}`, that makes it an array.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
