    Dumping fields into variables

    I have a file that we are supposed to use as input. It looks like this:
    Code:
    name:curriculum:gradyear:ssn:dob
    I'm going to read it in a buffer, but trying to find the logic to seperate the fields and then place in a variable. I was thinking something like:
    Code:
    if(ispunct(buf[x]) != ':') 
         strcpy(s->name, buf);
    Any suggestions is greatly appreciated!

    Well you could use
    - strtok(), but watch out for it modifying the source string. You need to copy the results elsewhere ideally.
    - sscanf() with a scan-set conversion. For example
    Code:
    sscanf( buff, "%[^:]", name );
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Hmmm, strtok(). Unaware of that function. Anyone might have an example on how its used?

    I'm aware of keyword searches. I just figured someone(thanks sand_man!!) had a quick link.
