<STDIN> stands for standard input. It can be abbreviated by using simple <>. By declaring a scalar variable and setting it equal to <STDIN> we set the variable equal to whatever will be typed by our user at the command prompt.
print"enter your name : ";
$name=<STDIN>;
if($name cmp "abdullah")
{
print "Your name Match With : ".$name."\n";
}
else
{
print $name. "Not match :\n"
}
print"enter your name : ";
$name=<STDIN>;
if($name cmp "abdullah")
{
print "Your name Match With : ".$name."\n";
}
else
{
print $name. "Not match :\n"
}
