Hi Anant,
I want to search whether a scalar '$a' contains any one of value of an
array
'@arr'.
How it may be done?
as its not correct : print "found" if $a =~ /@arr/;
#!/usr/bin/perl
use strict;
use warnings;
my @arr=qw(fry ring apple law);
print "Enter the string you are searching for:";
chomp(my $search=<STDIN>); # you may have to check, if input is not string
grep {print "found: $_" if/\b$search\b/}@arr;
#grep compare your search with each array element
# using $_ and then print out if item is found.
This is a miuse of the grep operator, which is filtering @arr according
to the expression in the braces and returning a new list. But you are
throwing away that list and using only the side effects. It should be
written
/\b$search\b/ and print "found: $_\n" for @arr;
