Question

I don’t want to learn regexps only for this particular problem.
I need to find some ‘/*N*/ ‘ comments through C++ files.
Can someone write a regexp which finds such comments?

Answer 1

Try this regex :

/\/\*(.*?)\*\//

This is how it works :

\/    <- The / character (escaped because I used / as a delimiter)
\*    <- The * character (escaped because it's a special character)
(     <- Start of a group
  .     <- Any character
  *     <- Repeated but not mandatory
  ?     <- Lazy matching
)     <- End of the group
\*    <- The * character
\/    <- The / character

Edit : It doesn’t handle \n nor \r\n, if you want it to then consider @Alex answer with the m flag.
