accessor&mutator functions

i need some help with these two functions can anyone please help?
Given the following class:
class Recording{
private:
int tracks;
float tot_time;
char year_issued;
char *Artist;
char *Title;

write accessor and mutator functions for: tracks: cannot be less that zero or greater than 16
year_issued: seen as standard (i.e. 2004) but stored internally as years since 1950 (2004 is 54)

if someone can please help with this i would really appreciate it

Accessors are methods that grant you access for read/write the private/protected data members. So for track:

Code:

---

public:
  int GetTracks() const
  {
    return tracks;
  }

  bool SetTracks(int _tracks)
  {
    if(_tracks<0 || _tracks>16)
        return false;

      tracks = _tracks;
      return true;
  }

Sorry, but I don't know what "mutators" are. :sick: I'm not familiar with this term.

In your example, bool SetTracks(int _tracks); is a mutator. This word is sometimes used in OOPspeak, but it has not made it into the dictionary. I looked in two of them and did not find this word.

guys,

thanks for the help that sheds a great deal of light for me, for i am new to programming
