If I were you, I'd start by defining exactly what you mean by "dictionary".

first of all thanks for replying...A dictionary from japanse romanji to english and vise versa..and the dictionary data base would be from a single text file....my main prob is how do i get a specific line from that text file
..:D

Well what you really need to do is to create a very large HASH TABLE where in a key has two references ie a word types in japanese(key) with references as the languages you would want to translate that into(meanings). You can work out your needs and the resources and then decide as to which method to choose.

Member Avatar for jeetthedream31

surender ur program is working but there is still a problem that we have to add words in the dictionary...this can also be possible using simple coding if a person have knowledge about structure....but i want to know that is there any way in which we can add words without a mannual adding?its very urgent for me?plz reply?

The earlier posts are from 2009, so I doubt they will answer your questions.

You need to start a new thread with your problem, and let this one be buried, again. ;)
