Hello All,
Hello,
I would like to know how to access character from string lateral.
Say I have
$foo = "From Big Brother Africa";
I would want to print each of the characters of $foo on its own.
In some languages string type is just array/list of characters. What is it
in Perl?
A string.

$ perl -le'my $foo = "From Big Brother Africa"; print for split //, $foo'

$ perl -le'my $foo = "From Big Brother Africa"; print for $foo =~ /./sg'
