Kwic implemtation...help

[Ironbru]

Hi folks one of the dreaded newbies. I have checked the faq's, and searched all over the place, so hope some one can help.

I have to implement a KWIC (Keyword in Context) program in C
I have completed this in Perl, as the first part and now have to redo in C. My input is in a file like this

1
::
ignore
words
::
look in these sentences for ignore words
another sentence

This produces 3 seperate fields, divided by "::"

I need to read the number in..store it..easy

I need to read in "::" and check to see if it is one..and disregard it

1. One problem I am having is how do I check characters against others?

2. Another, how do I get it to loop until it reaches the second set of "::" ?

3. The trickiest stuff the kwic index... Need to split up sentences,and check against each word for existence of keywords.

4. Also tricky, after keyword is identified, how do I replace it in the proper place in capitalized form.

Any advice appreciated. Esp on input and array manipulation..

If you can do it in Perl, then there's no reason you can do it in C Just review your Perl source and try to look into C's "string.h" library. Lots of string maniputlation functions there.

You're going to love this. It isn't as hard as you're expecting.

First, check out fscanf here: http://msdn.microsoft.com/library/de...nf_fwscanf.asp

Then check here:
http://msdn.microsoft.com/library/de..._functions.asp

after that, here:
http://msdn.microsoft.com/library/de..._functions.asp

I think that's all you really need to do the first few parts. Then you'll need some string comparision functions...look up the STL functions, run a board search for them, or I'm sure someone here will help you. I don't know them myself For #4 though... not sure what you mean, but Toupper() will capitalize a letter for you.

You'll probably be better off using fgets() instead. The scanf() family have trouble returning all the data if not used properly whereas fgets() will return one full line from the file.
