<title>DELETE keyword</title>
<!-- Changed by: Martin Leslie, 14-Mar-1996 -->

<center><h1>DELETE keyword</h1></center>
<hr>
<p>
The <b>delete</b> keyword replaces the
<a href="../../C/FUNCTIONS/free.html">free</a>
function in C and will release storage reserved with
<a href="new.html">new</a>.
<p>
<center>
<table bgcolor=ivory width="80%" border=1>
<tr>
<td>
<pre>
int *ptr1; // Declare a pointer to int.
ptr1 = new int; // Reserve storage and point to it.
float *ptr2 = new float; // Do it all in one statement.
<b>delete</b> ptr1; // Free the storage.
<b>delete</b> ptr2;
struct House // Declare a complex structure.
{
int Floors;
int Windows;
};
House *ptr3 = new House; // Reserve storage and point to it.
<b>delete</b> ptr3;
</pre>
</td>
</tr>
</table>
</center>
<p>
Blocks or arrays of storage can also be freed as shown in the
next example.
<p>
<center>
<table bgcolor=ivory width="80%" border=1>
<tr>
<td>
<pre>
char *ptr
ptr = new char[80];
<b>delete</b> [] ptr; // Free the storage.
