I need my code made into a Heirarchy Chart.

C++ CODE:

#include

string title;

string genre;

float len;

};

void menu(){

cout<<"Enter the corresponding key for the operation you want to do ";

cout<<"1. Manage Playlist ";

cout<<"2. Manage Songs ";

cout<<"3. Display Playlist ";

cout<<"4. Exit the program. ";

}

string manage_playlist(){

string pName;

cin.ignore();

cout << "Insert a name for this playlist: ";

getline (cin, pName);

cin.clear();

return pName;

}

void manage_songs(music arr_str[],int i){

for(int k=0;k<3;k++,i++)

{

cout << "Insert the title of the first song: ";

cin.ignore();

getline (cin, arr_str[i].title);

cout << "Insert the artist name of the first song: ";

cin.ignore();

getline (cin, arr_str[i].artist);

cout << "Insert the genre of the first song: ";

cin.ignore();

getline (cin, arr_str[i].genre);

cout << "Insert the length of the first song: ";

cin >> arr_str[i].len;

}

}

float playlistAverage;

cout << "Choose your favorite genre" << endl;
