The higher level functions provide you with ease of usage also, functions like
fopen()provides you with in-built I/O buffering unlikeopen(). The I/O buffering ensuresfopen()is much faster thanopen().Apart from the above distinction If you have just file descriptor, you should use read, write etc, While If you have a
FILE *, you should use functions likefread,fwriteetc.
