DELETE keyword

+
+

+The delete keyword replaces the +free +function in C and will release storage reserved with +new. + +

+

+ + + + +
+
+
+    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.
+    
+    delete ptr1;                // Free the storage.
+    delete ptr2;
+    
+    struct House                // Declare a complex structure.
+    {
+        int Floors;
+        int Windows;
+    };
+    
+    House *ptr3 = new House;    // Reserve storage and point to it.
+
+    delete ptr3;
+
+
+
+

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

+

+ + + + +
+
+
+    char *ptr
+    ptr = new char[80];
+    
+    delete [] ptr;          // Free the storage.
+
+
+
+
