  Mr Schildt is, as he is so often in fact, in error here.

  To quote the C standard :

       7.9.3  Files

          [...] When a stream is unbuffered, characters are intended to
          appear from the source or at the destination as soon as
          possible.  Otherwise characters may be accumulated and
          transmitted to or from the host environment as a block. When a
          stream is fully buffered, characters are intended to be
          transmitted to or from the host environment as a block when a
          buffer is filled.  When a stream is line buffered, characters
          are intended to be transmitted to or from the host environment
          as a block when a new-line character is encountered.

          [...] When opened, the standard error stream is not fully
          buffered; the standard input and output streams are fully
          buffered if and only if the stream can be determined not to
          refer to an interactive device.

  From the above, it can be seen that CSet is in fact correct.

  The ISO C standard only requires that the standard output stream *not*
  be *fully* buffered when it is determined to be connected to an
  interactive device.  It can quite legally be *line* buffered, which is
  exactly what it is in CSet.

  The simple (and obvious) solution is to use fflush(stdout) between
  every printf() that isn't terminated by '\n' and the following
  scanf().

  Another solution is to use setvbuf (q.v.) to switch it to being
  unbuffered.
