    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.

    You need to get rid of the global variables! That's just bad programming. Make a List struct, init it in main and pass it around.

    I think maybe the structure of your list is wrong. You have a list of files where each node contains an array of operations. I wonder if you were supposed to have a list of operations instead of an array.
    Code:
    a.png -> b.png -> c.png -> 0
      |        |        |
     copy    layer    paste
      |        |        |
     crop      0      delete
      |                 |
      0                 0
    You could get rid of a lot of code duplication by using arrays instead of numbered variable names.
    If you want the truth to stand clear before you, never be for or against. - Sent-ts'an
