Hello,
i tried to create a double_linked_list,
but somehow it doesn´t work as expected.
I wrote 2 routines,
one to show all list-members from the beginning
and one show then from end.
But the routine that should show all items beginning by the end of the list
only shows some members
and i can´t get the point where the app drops the rest..
Project attached.
Thanks,
Tino
Ok I'm posting the corrections, I can't easily follow your code also because my german is at level 0.
Anyway I introduced a lot of semplification, I would invite you to try to code in a more plain way, you put a lot of code where few lines can do the job.
As some games say "improve yourself" you're at good point ;).
Hello frankie,
First a big -Thank You-,
i tried a tutorial, changed some parameters
and ended in total confusion..
The "Begining"/"Ending" stuff was a test to see
if the pointers work as imagined
and should lead to a delete routine ("loeschen" = "delete"),
which after your contribution seemed (very) easier to be build.
Here´s what i made out of it,
hope there are no more bugs ..
ps:
Now that you brought the term "insert in the middle",
i´m thinking how that could be realised.. ?
There are 2 interesting possibilities:
1st - Insert Item by index,
2nd - Insert Item before/after Item..
When thinking about the indexing,
i wondered how that should be done..
..counting via global variable
..a loop iterating each time through the list
..or even using an array ??
Do you know if there´s a standard / better solution ?
pss:
Please let me know what you mean by "plain" Style,
the basic framework of this sample is out of a tutorial,
i just changed the pointer-handling
because the original based all functions on a pointer which used to be the actual Item
really confusing and only working linear..
(no chance to add an item, delete, add again..)
Thanks,
Tino
Tino I posted a working double linked lists handling library that emulates OOP programming with many of the features that you required in the 'Tips & Tricks' thread.
I hope this would satisfy your needs.
