Could someone help me out here?
I am trying to get my program to delete arrays within
a structure named item. It is for an assignment at school
and I just can't figure this one out. For some reason, when
I run through to the print option, I notice that the program
is not recognizing my attempt to errase in the delete function.
Thanks for your help.
