Question

USE C++ 

Declare a Song struct to store the data for a single song (make it a private member), and you must have anarray of Song structures as a member variable.

Player(string name, float size) a constructor for the class. ’name' is a name for it
'size' is a maximum capacity in Mb.

addSong(string band, string title, string length, float size) a function for adding a new song.

'band' is a name of the band
'title' is a name of the song
'length' is a time length of that song in a '1:23' format (“mm:ss") 'size' is a size of the song in Mb

Return true if the song was added and false if there was not enough space (memory) for it or there was a song with the same band and title already in that device or if the device already has 1000 songs in it.
