STDIN is okay. But do you think this program will work? Did you run this program and check?
Still there are very basic syntax errors in your program and this program will not work. You could have found out if you have executed this code
coding for print 47
#!/usr/bin/perl
use strict;
use warnings;
print "Enter a number:";
my $input = <STDIN>;
chomp $input;
if ( $input == 47 );
print "number is 47\n"
else
print " number does'not match . enter number again"

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).
