Hello,
I'm writing an abstract program that keeps a record of Names and Phone numbers. I've created a Record class that inherits a Name and Phone class. All the functions work great except for delete. The delete function is supposed to replace the record value with "DELETED". The program says the record is deleted but its value is not changed. Why is this happening?
Any help is appreciated. Thanks so much.
