So I am trying to write a class Songs which takes a string title, int duration and a pre-defined scoped enum class Vibe as parameters:

enum class Vibe {Sad, Happy, Aggressive, InLove};

When Vibe is empty, I would like it to be automatically set as InLove.

Wrote constructors which either title and duration oder title, duration and Vibe. When Vibe is empty, I want it set to InLove automatically. So I tried to use a default constructor like this:

Song::Song(const string& title, const int& duration, const Vibe& vibe = vibe::InLove) : title{title}, duration{duration}, vibe{vibe} {
  //conditions for constructors
  };

Song::Song(const string& title, const int& duration) : title{title}, duration{duration} {
  //conditions & runtime_errors again
  };

Compiling works but it just takes the first parameter of the Enumeration Sad as a default when Vibe is left empty.

I tried this:

vector<Song> sl;
sl.push_back({"Still loving you",386});

s1 should take the parameters song = "Still loving you", duration = 386 and vibe = InLove, however it ends up having song = "Still loving you", duration = 386 and vibe = Sad.

Could someone tell me what I’m doing wrong?
