I have written this C++ program. When you enter artist, song and song length it asks if I want to enter another, so i enter y for yes and I enter the same information. Now when it asks if i want to add another song i hit no and select display play list option. It shows the playlist but the name of the artists from the play list is missing

please help.

all information for the items entered shoud be displayed.
