+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>.

+<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;

+Blocks or arrays of storage can also be freed as shown in the
