INCREMENTAL VARIABLES IN UNIX (BASH)

Hi All,

Im trying to separate digits from a number and assign the number to different variables.

eg: if number is 243

then

a1 = 2
a2 = 4
a3 = 3

Im able to get the separate numbers but not able to generate a variables on the go and assign the values to them. Can some one please help me on this issue. Below is my code

Code:-

#!/bin/bash

read n

for ((i=1;i<1000;))
do

###############
i=$(($i*10))

y=$(($n%10))
echo $y

################

x=$(($n-$y))
echo $x
n=$(($x/10))
echo $n

#############
for j in {1 …3}
do

v[j]=$y
echo $v1 $v2 $v3

done

done
#############################

Thanks in advance
