Answer / Preeti Arya
Perl provides various functions to perform file operations, such as opening, reading, writing, appending, and closing files. Opening a file is done using the open() function.nnExample: `open(my $fh, '>', 'example.txt') or die "$!"; print $fh 'Hello World'; close($fh);` This opens the file 'example.txt' in write mode, writes 'Hello World', and then closes it.
