      It means that it is a destructor for class CcMessage.

      cheers,

          Since you say you are a beginner, I can't tell if you know what a class
          means - if you do, a function like that inside a class named CcMessage
          gets called each time an object of that class goes out of scope - it
          performs certain cleanups needed to destroy the object.

              It's a destructor. Look it up.

              No need to 'forgive' you, only to recommend you
              get a good textbook or two about C++. It's virtually
              impossible to learn it without one.

                  It means that this is the destructor function for class CcMessage. It
                  will be called when an object of class CcMessage is destroyed.
