Hi there,
I have an assignment in which the first part requires me to store coordinates in a .txt file in a linked list data structure.
The text file has coordinates laid out as follows:
1 1 5
1 2 4
1 3 87
1 4 76
2 1 54
etc etc, basically in the form x y z
I need to know how to create a 3d linked list structure to store these, or if this is even the best approach to take! I can't use an array because I don't know how many elements there are.
Once this structure is made I need to implement a local search simulated annealing strategy on it - but that's another problem.
Any help would be greatly appreciated.
Regards,
Chris.

You might have a look at an oct-tree data structure.
kind regards,
Jos
Perhaps your first step should be to create a Point class with int x,y,z as attributes and then simply put the points into a LinkedList.
@JosAH
I also got some fancy ideas when I first read the post. Then I kept re-reading it again and decided that they don't want to display the linked structure at all. Maybe I was wrong but I think this one is one of those very simple ones explained in a complicated manner.

Hi all,
Can a linked list be a member of a structure?
If so, when I add or remove an element from the linked list, the size
of the structure will change. Will it cause any problem?
Thanks a lot.

I'm trying to creat a data structure, that can be either a integer,
double, string, or linked list. So I created the following, but don't
know if it is the data structure itself causing problems, or something
I am doing in the rest of the program.
This is the data structure.
struct node

char type;

I am looking for a data structure that I need to use as follows.
Suppose I am looking for node A. When I perform a lookup for node A I
also want information about the node previous to node A( as per the
lookup data structure ordering scheme). Is there anything that I could
use for this. Using a doubly linked list is not looking good as I can
have a large number of elements in my linked list.
Thanks in advance,
Peter

In the course of an assignment, I learned the hard way that I shouldn't try
to free a malloc'd member of a malloc'd structure after having freed that
structure (i.e., free( structure ); free( structure->bufferspace ) ).
My question is, if I free just the structure, will the (e.g.) bufferspace be
freed implicitly, or do I have to (as I currently am) free the members
first?
Thanks.

After executing the following code I receive the errors:
a.c: In function `insert':
a.c:59: error: incompatible types in assignment
I have no problem when first_name in the structure is an int. I can
easily assign a default value in the insert function. But I would like
to allow full strings to be sent to the field from the insert
function....Any ideas?

Hi all.
Ok, I'm using VB6 but I think the answer to this (if there is one) is more likely to be found in the Access forum.
I have a situation where I've got tens of millions of records, spread over a bunch of separate databases. I don't have a choice about this, as the data is simply too large for a single MDB. As yet, I'm not prepared to go to SQL Server. Possibly in the not-too-distant future, but we'll see. In the meantime, I have this...

Create a linked list data structure library to hold strings. Then library should support the following linked list operations.
Create() – Creates the linked list
Insert() – Insert a string into the linked list
Delete() – Deletes a string from the linked list
Search() – Search for a string and return 1 if found otherwise return 0.
isEmpty() – Returns 1 if the list is empty and 0 otherwise.
Display() – Display all the strings in the list.

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
