Yes a simple exp is the link list.
struct node
{
int data;
struct node *link;
}
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 Null pointer has the value 0. void pointer is a generic pointer introduced by ANSI. Before ANSI, char pointers are used as generic pointer. Generic pointer can hold the address of any data type. Pointers point to a memory address, and data can be stored at that address.
a USB laser pointer is simply a laser pointer powered by the USB socket.
The pointer.
Void Pointer is a General purpose pointer ,that does not have any data type associated with it and can store address of any type of variable. Declaration: void * pointer_name;
Yes, it is quite common. Example: struct List { struct List *Next; int value; } typedef struct List List; Example2: typedef struct Tree Tree; struct Tree { Tree *left,*right; int value; };
A structure is a collection of primitives or other structures. A pointer is a memory address. Comparison of the two is like comparing bowling balls to cinder blocks. You can say that a structure defines the layout of the data, while a pointer points to data that is a particular structure.
It is a pointer that points to a member of a structure.
By declaring an integer pointer you are declaring that any non-zero reference stored in the pointer is guaranteed to be an integer reference. In order to guarantee the reference is actually a structure, the pointer must be declared as such, because casting an integer to a structure can never be regarded as being type-safe.
No
Create a pointer of the type (pointer to struct) and assign the address of an instance of the structure to your pointer: typedef struct x { /* ... */ }; struct x my_structure; struct x* ptr = &my_structure;
Pointer is a variable that stores the address of another variable. Since pointer is also akind of variable, thus pointer itself will be stored at a different memory location.
A pointer in itself is not an object, because it is not an instance of a class. Of course you can define a class which has only one member, which is a pointer. class Pointer { public void *ptr; }; Pointer p, q, r;
A pointer is a variable that holds address information. For example, in C++, say you have a Car class and another class that can access Car. Then, declaring Car *car1 =new Car() creates a pointer to a Car object.. The variable "car1" holds an address location.
Not in C, no.
Your question makes no sense.
