Thread: Delete In Double Linked List

Please Help Me to Make DELETE Function DELETE it from Linked List


Detail Requirement:

1. The iPhotoShoppe Application must be created using Menu.

1. Open Picture
2. Checking Metadata
3. Delete
4. Exit

1. In menu Open Picture there are conditions:
   
   1. Prompt user to input picture name for example

filename.extension example (hello.jpg).

1. Validate extension, only ‘jpg / png / gif’.
2. Random 7 editing process (‘paste’,’delete’,’copy’,’crop’,’layer’).

Insert to Linked-list.

1. In menu Checking Metadata there are conditions:
   
   1. There is error saying No Picture Yet if no data entered yet.
   2. Loop all editing from all the picture. Set tag as hoax if contain min 2 layer and 2 crop.

1. In menu Delete there are conditions:
   
   1. Delete all picture tagged with hoax start from the last picture entered.
   2. Remove all picture that contain ‘delete’ in editing process more than 3 times.
   3. Print all picture (not yet deleted), and All picture deleted separately.
