ehdonhon is right -- you're always better off here if you include something you've tried, especially if you tell us what you got from it, so we can see how it differed from what you say you want (this sometimes helps us get a better idea of what you really want).

In fact, I'm only guessing now that you might want something like this:

@another_array = map { $_ * $number_from_stdin } @large_array;
[download]

or maybe you'd be more comfortable with something less compact:

foreach my $val ( @large_array ) {
   push @another_array, $val * $number_from_stdin;
}
[download]

which does the same thing, but may be less mystifying to a larger audience of programmers who may be unfamiliar with Perl.

So, have you been reading any relevant books or documentation? You might find that helpful as well...

• 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.
