When we call non static method with respect to class object then this pointer is created which keep the reference of that object.

A double pointer is a pointer which points to another pointer which points to an object.For example:Foobar** foobar = NULL;This means that somewhere in memory, the class foobar has been created. The variable 'foobar' now points to a pointer to that memory. However, in this example, the pointer is created as 0.

pointer r the variables created in RAM which store the address of a another variable


its pointer created for high safety that cant be find by anyone.


Pointer is simply a variable that stores the memory address of another variable. Pointer to pointer means double pointer ,pointer that points to another pointer variable.

Pointer is a variable that is used to store the memory address of another variable. There are differenr types of pointers: NULL pointer THIS pointer VOID pointer NEAR pointer HUGE pointer FAR pointer WILD pointer


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.

Pointer to Pointer is a double pointer, denoted by (**). Pointer stores the address of the variable and pointer to pointer stores the address of a pointer variable and syntax can be given as int **ptr2ptr;


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


Double pointers are better known as pointer-to-pointer types. You use pointers to store the memory address of an object but when the object is itself a pointer, you need to use a pointer-to-pointer in instead. Pointer-to-pointer types are typically used when passing pointers into functions. Pointers allow you to pass objects to functions by reference but the pointer itself is passed by value. If you want to pass the pointer by reference, you need to pass a pointer-to-pointer.


A pointer only holds an address information (location) in the memory. if a pointer holds points another pointer then it is a pointer to an other pointer. Pointer holds an address in the memory so in that address there is an other location information that shows another location.


A pointer points to another pointer in the same way that a pointer points to a non-pointer object. Start with a pointer to an object... int a; // the object int *pa = &a; // the pointer pa; // is the value of the pointer *pa; // is the value of the object Now, create a pointer to a pointer to an object int a; // the object int *pa = &a; // the first pointer int **paa = pa; // the second pointer a; // is the value of the object pa; // is the value of the first pointer *pa; // is the value of the object using the first pointer *paa; // is the value of the second pointer **paa; // is the value of the object using the second pointer And so on and so forth... Just don't forget to initialize each pointer along the way!


A Pointer is a Variable that holds a memory address, usually the location of another variable in memory. A pointer to pointer is known as double pointer.


pointer is the variable that holds the address of another variable


Double (**) is used to denote the double pointer. As we know the pointer stores the address of variable, Double pointer stores the address of any pointer variable. Declaration : int **ptr2Ptr;


Void pointer can hold the address of any kind of pointer. But we can't operate on void pointer
