hi guys.. can you help me with my assignment?

my proff told me to make a dictionary prog that can do the following..

1. Add new word and definition
2.delete word and its definition
3. view all words and its definition
4. Update word and its definition
5. Search a word.

this is what i have started guys..

but i still don't how to make this work.. its so messy :(

it runs but its a mess. hehe..

some are leaved blank guys.. i dont know what to do.. and i donot know how to store :(

Is there a reason you have used a SingleLinkedList?
I personally would have gone for something more strongly typed:

//private collection that you can add/update/remove
private List<DictionaryEntry> _dictionary;

//class to store each entry with public properties to access values
    public class DictionaryEntry
    {
    
        private string _word;
        private string _description;

        public DictionaryEntry()
        {
            _word = string.Empty;
            _desc = string.Empty;
        }
        public string Word
        {
            get { return _word; }
            set { _word = value; }
        }
        public string Description
        {
            get { return _description; }
            set { _description = value; }
        }
    
    }

Linked Lists are usually used to store data where the order is important such as stacks/queues/etc.
I dont see a reason to maintain links between your dictionary items so a List is a better way to go :)

so it means... the LinkedList it no use at all? thanks..

btw, can you teach me how to store data?

cuz i think using

variable = Convert.ToString(Console.ReadLine());

wont work..

Hey,

Firstly, im glad to hear you got it working :) Sorry i didnt reply, i had a 50 mile charity bike ride at the weekend so i was away from forums...your thread kinda slipped under the radar after that.

I'm still not entirely sure why you used Linked Lists though. Unless i'm missing something, your nodes arent related to one another; when you look for a node you arent interested in which nodes were added before it. Linked Lists retain thier order making them useful for things like queues and stacks.

What you have done here could easily have been done using a List<T>.
Obviously, if its all working, dont go tearing it apart to rewrite it ;)
But for future reference, i'd recommend looking into collections as they are much easier to use for this sort of project. You create your list then you just use .Add(), .Remove(), .Find() methods.

Remember to mark the thread as solved since you answered your own question :p
