Hi Perl Monk,

I am intend to remove C and C++ style comment from a C code. In the below perl script I am reading from a file, modifying and writing into another file.

Now my question I need to write into the same file as when I modify line. If I open the file in write mode it is not working. Please help me how do I write into the same file and at the same line. 

#!/bin/perl5.8.6

$flag = open(file1, "main.c");
$flag2 = open(file2, ">main_out.c");

if(flag && flag2){
while(!eof(file1)){
  $/ = undef;
  $_ = <file1>;
  s#(/\*.*?\*/)|//[^\n]*|("(\\.|[^"\\])*"|'(\\.|[^'\\])*'|.[^/"'\\]*)#
+defined $2 ? $2 : ""#gse;
  print file2 ($_);
}
}
 
 close(file1);
 close(file2);
