  Re: what is the difference between NULL & NUL keywords in C?
Answer
# 1		 NULL is a macro defined in <stddef.h> for the null pointer.
<br>NUL is the name of the first character in the ASCII
character set. It corresponds to a zero value. There?s no
<br>standard macro NUL in C, but some people like to define
it. <br>The digit 0 corresponds to a value of 80, decimal.
Don?t confuse the digit 0 with the value of ?? (NUL)!
<br>NULL can be defined as ((void*)0), NUL as ??. <br>

NUL is the name of the first character in the ASCII
character set. It corresponds to a zero value. There's no
standard macro NUL in C, but some people like to define it.
