The while test on the value of days is made after the conversion to seconds is done so when you enter q you are trying to convert it to seconds. you could do a few things, here is one that keeps a while loop...

#!/usr/local/bin/perl -w use strict; while (1) { print "Please enter a single positive integer that represents a number of da +ys, that you wish to convert into seconds. ,(enter q to quit): "; chomp (my $days = <STDIN>); $days =~ s/\+//; # allow them to enter +12 if ($days eq "q") { last; } elsif (($days =~ /[^\d]/) or ($days eq "")) { # days contains an non digit character or is empty print "\n!!! You must enter a positive integer.\n\n"; } else { my $seconds = $days * 86400; my $plural = ($days == 1) ? '' : 's'; print "\n$days day$plural = $seconds seconds.\n\n"; } } print "Goodbye\!\n\n";

update to catch entry of 0

Change the elsif check to this if you want to prevent them from entering zero days
} elsif (($days =~ /[^\d]/) or (not $days)) {

Use:  <p> text here (a paragraph) </p>

to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
