Perl to access character from string
This it to pring 'i' character.
Code:
#!/usr/bin/perl
$str="This is perl";
print $str[2];

Must i split the string to access a character from string?
How can i print characters individually using a for loop?

Code:
print substr $str,2,1;

For loop:
Code:
for $i (0..length $str){print substr $str,$i,1}

Alternatively, you can also do it with a while loop and regex pattern match -

Code:
$
$ perl -le '$str="This is perl"; print $1 while ($str =~ /(.)/g)'
T
h
i
s
 
i
s
 
p
e
r
l
$
$
