Hello Khabza,
" I want to substring words, I might be using wrong terminology. But I tried
the following example the only problem I have it cut word any where it
likes. eg "breathtaking" on my string is only bre."
-- If you count your $string alphabeth by alphabeth from 0 to 100 including
every space then you will see that your "substr" function is right! I
believe that reg exp can also help as mentioned by Rob
Coops<khabza....@gmail.com>,
but you may have issues getting to your preffered destination on the
$string.
Without altering your code so much check the codes below maybe it could
help!
#!/usr/bin/perl -w
use strict;
# this is your string to examine
my $string = "This is an awe-inspiring tour to the towering headland
known as Cape Point. Magnificent beaches, breathtaking views, historic and
picturesque coastal ";
#ask the user to input the last word
#of the string they are looking for
# e.g if the want the following "This is an awe-inspiring tour to"
# the user will enter the word "to"
print "Enter the extends of your string:";
chomp(my $newStr=<>);
$newStr=checkStr($string,$newStr); #subroutrine to check user input
print substr $string,0,(index($string,"$newStr")+length("$newStr"));
sub checkStr{
my ($orig,$search)=@_;
foreach((split/ /,$orig))
{
if($_ eq $search){return $search}
}
}
Hello Rob Coops,
Am sorry for the mix up!
Thanks
