C beginner

john_g83

Just getting back into c coding after a long time (and wasn't very good to begin with).

What I need to do is take in a text document (50 or 60 words) and parse it so that each individual word is sepperated from one another.

Using strtok I have been take words from the original file and write them individually to another file. i.e:

"Due to the recent increase in online auction fraud it is now
mandatory for you to verify your account "
Written to new file:
Due
to
the
recent
increase
in
online
auction
fraud
it
is
now etc.

what I need to do is put each of these words into an element of an array so that each word can be analysed individually. Can this be done using structs or am I missing something very obvious.
Any help would be greatly appreciated
Regards
John

char str[] = "Due to the recent increase in online auction fraud it is now mandatory for you to verify your account ";
   char delims[] = " ";
   char *result = NULL;
   result = strtok( str, delims );
   while( result != NULL ) {
       printf( "result is \"%s\"\n", result ); //you won't need this bit, only to verify that its working - but you knew that :)
       result = strtok( NULL, delims );
   }

Adapted from http://www.cplusplus.com/ref/cstring/strtok.html, so appologies if it doesn't work. I don't know C\C++, so I was just working with what I saw.

Ya that should work fine, i would make one change though, if the delimiter is only a space then you don’t need an array just a point to a char.

thanks for the reply guys. Unfortunately I don't think the method mentioned by doodle will work as the code needs to be adaptable to work on different text segments/text files. Had a brainstorm in bed last night that I could analyise each word as it is tokenised and then write to a new file (basically any word > 6 or 7 letters will be replaced by a synonym to modify the text file). Jessy am using all types of punctuation as delimeters as I need ti identify individual words.
Will try the above and let y'all know how I get on. Thanks again for the help

The way strtok works is by replacing the tokensing character with '\0'. So you should be able to do strtok and then make each item it returns an element of an array of pointers. That what you're looking for?
