Assigning an initial value to a pointer variable. Example:
int *p= NULL;
Declaring a pointer involves four key parts: Data Type: Specifies the type of data the pointer will point to (e.g., int, float, char). Asterisk (*): Indicates that the variable being declared is a pointer. Pointer Name: The identifier used to reference the pointer variable. Initialization (optional): Assigning the pointer to the address of a variable using the address-of operator (&) or setting it to nullptr for safety. For example, int *ptr; declares a pointer to an integer.
When a declared variable receives a value to hold. i.e. int lalalala; lalalala = 0; //initialization of lalalala
Lazy initialization is a process by which an object is not initialized until it is first called in your code. The .NET 4.0 introduces a new wrapper class, System.Lazy<T>, for executing the lazy initialization in your application. Lazy initialization helps you to reduce the wastage of resources and memory requirements to improve performance. It also supports thread-safety.
Answer is; initialization *** Edit*** Initialization is correct. Page 59 Programming Logic and Design by Tony Gladdis
...are important things in programming. Example: extern int variable; /* declaration */ int variable= 8; /* definition with initialization */

You can find the number of elements and free elements in a pointer array by iterating through the array and counting the number of elements that are null versus the number that are non-null. Of course, this technique's success depends on proper initialization of each element, i.e. when first created or when deleted, it must be set to null.

Initialization is nothing but assigning some value to a parameter. ex :- int a; // Defination of an integer variable a = 3; // Initialization of the variable a

The general order of initialization is:Base class objects (if present)Member data objectsConstructor function code
1. pointer to a constant means you can not change what the pointer points to 2. constant pointer means you can not change the pointer.
Perhaps an example will help. extern int value; /* declaration */ int value; /* definition */ int value= 20; /* definition with initialization */
Example: int x; -- integer int *px= &x; -- pointer to integer int **ppx= &px; -- pointer to pointer to integer int ***pppx= &ppx; -- pointer to pointer to pointer to integer
