<h1>srand function </h1>

<hr>
<p>
<b>srand</b> seeds the random number generation function
<a href=rand.html>rand</a>
so it does not produce the same sequence of numbers.
<pre>
Library: stdlib.h
Prototype: void srand(unsigned int seed);
Syntax: unsigned int seed=10; /* seed value */
srand();
</pre>
<hr>
<h2>Notes</h2>
<ul>
<li>
Obviously the seed has to change every time the program is run.
One way to do this is to feed it the O/P from <a href=time.html>time</a>
</ul>
