Question

I need to do mimic the functionality of the following Perl code

if($file =~ /^([^_]+)_([^_]+)_MA_(\d{4})(\d\d)(\d\d)_(\d\d)(\d\d)(\d\d)\.MA$/) {
  my ($radar, $beam, $year, $month, $day, $hour, $min, $sec) =
      ($1, $2, $3, $4, $5, $6, $7, $8);
  my $file_ts = sprintf("%04d-%02d-%02d %02d:%02d:%02d",
      $year, $month, $day, $hour, $min, $sec);

  # ...
}

in C++. Which function do I use for it?

Answer 1

Same as in Perl:

char file_ts[1000];

snprintf(file_ts, "%04d-%02d-%02d %02d:%02d:%02d", year, month, day, hour, min, sec);
