+<h1>free function </h1>
+</center>
+<hr>
+<p>
+<b>free</b> is used to return allocated memory to the system. 
+<p>
+<hr>
+<pre>
+	Library:   <a href="funcref.htm#stdlib">sdlib.h</a>
+
+	Prototype: <a href="../SYNTAX/void.html">void</a> free(void *s);
+
+	Syntax:    char *StrPtr;
+		   StrPtr = (char *) malloc(100);
+                   free(StrPtr);
+
+</pre>
+<hr>
+<h2>Notes:</h2>
+<ul>
+<li>If you use <a href="malloc.html">malloc</a> inside a loop and dont <b>free</b>
+the memory, you run the risk of the program crashing. 
+<p>
+<li>If a program ends without issuing a <b>free</b>, any allocated memory 
+is returned to the system.
