Reason is that you are reading input files by lines (the s in reqex is useless) and do the print in if statement for reqex. So even if it matches what you need it does not print the rest of lines because reqex won't match for them.

I would suggest something like that (not tested): 

my $c_file = "NO MATCH";

while (<$hfile>)
{  
    my $line = $_;
    if ($line =~ /[DWEM]\s+.*?\s+(?:c|cm|M)\:($input_pid)\s+([^\.]+\.c
++)/s)
    {
        $c_file = $2;
        my $pid = $1;

    }

        if($input_string eq $c_file)
        {
           #check with input string
          print $ofile "$line\n";  #write the output in a output file
        }

}
