I have obtained whole sentence by using this. If the sentence like this

Sentence 1: Harry Protter; M; 15
Sentence 2: Peter Parker; M; 23

char wholeLine[45];
//obtain the whole string
fgets(wholeLine, 45, ptr);

how can I break up this sentence without storing the semi-colon and save
it into three different character array?

some one told me that it can be done by this

char rest_name[40];
rest_name = strtok( wholeLine, ';');

But It can't do it, anyone can guide me ? Thx

Dude..
Your query was addressed just a couple of days before in the same group.

Firstly, a buffer of 45 characters is rather mean. Unless there is a limit
imposed by your format, why not use 1024?

Secondly, strtok() returns a pointer to the portion of the string after the
separator, and replaces the separator with a NUL. It does not return an
array of characters.
It is quite a tricky function to use, so read your documentation carefully.
