please help for album class in c++

Upon instantiation, anAlbumobject receives the name of the file that contains the album of songs.This file has been written in binary format.The data in this file has been written in the following order:

• the first four bytes hold anunsignedvalue that specifies the number of songs in the album.
• the next set of four bytes each holdsunsignedvalues specifying the byte offset from the start of the file to each song in the file and finally to the byte immediately following the last song in the file.For four songs, there are five values of four bytes each.
• the next set of bytes holdscharvalues representing the notes in the songs in the album.The songs are concatenated to one another with no separator.
