<h1>rand function </h1>
<b>rand</b> will generate a random number between 0 and 'RAND_MAX'
(at least 32767).
<pre>
Library: stdlib.h
Prototype: int rand(void);
Syntax: int r; /* Random number */
r = rand();
</pre>
<hr>
<h2>Notes</h2>
<ul>
<li>
Rand will always produce the same sequence of numbers unless
<a href=srand.html>srand</a> is called to seed the start point.
<li>
RAND_MAX is only defined in ANSII header files.
<li>A non standard function <b>random</b> is available on the Sun.
