( [id://3333]=superdoc: print w/replies, xml ) Need Help??

Hi all

Thank you for your responses. I just tried the following. Took me a few searches, I also happened to get the brackets wrong for the array....used [ instead of (... and then went "heck, [ is for anonymous arrays..." hahaha. The map and grep took google searches to get it flowing back.

C:\>more first.pl #use warnings; #use strict; my @arr = (1..10); foreach my $num (@arr) { print "Index is: $num. Value is: $arr[$num] "; } #Another way print "\nWith a C like for loop\n"; for($num = 0; $num<= $#arr;$num++) { print "Index is: $num. Value is: $arr[$num] "; } my @divbytwo = map { $_ / 2} @arr; print "\n\@divbytwo = @divbytwo\n"; my @divbytwoo = grep { $_ % 2 == 0} @arr; print "\@divbytwoo = @divbytwoo\n"; C:\>perl first.pl Index is: 1. Value is: 2 Index is: 2. Value is: 3 Index is: 3. Value i +s: 4 Index is: 4. Value is: 5 Index is: 5. Value is: 6 Index is: 6. V +alue is: 7 Index is: 7. Value i s: 8 Index is: 8. Value is: 9 Index is: 9. Value is: 10 Index is: 10. +Value is: With a C like for loop Index is: 0. Value is: 1 Index is: 1. Value is: 2 Index is: 2. Value i +s: 3 Index is: 3. Value is: 4 Index is: 4. Value is: 5 Index is: 5. V +alue is: 6 Index is: 6. Value i s: 7 Index is: 7. Value is: 8 Index is: 8. Value is: 9 Index is: 9. Va +lue is: 10 @divbytwo = 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 @divbytwoo = 2 4 6 8 10

I think I better start from scratch :)

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
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 How to display code and escape characters are good places to start.
