`printf' writes to stdout, and stdout is line-buffered.  That means 
single characters aren't written.  If you want an immediate update, call 
`fflush(stdout)' after each `printf'.  Or switch stdout to be unbuffered 
by calling `setvbuf' before you start printing.  (This is explained in 
the FAQ btw.)
