C Programming - Pointers - Discussion

Pointer is a generic term which means "pointing to something".We can use pointer to store address of any variable or any function (Function pointer).
"Program Counter also known as instruction pointer (IP) in Intel x86 holds the address of instruction."

The answer can be summarized as follows...

[A] A keyword used to create variables -> Wrong. A pointer is NOT a keyword.
[B]. A variable that stores address of an instruction -> Wrong. Though a pointer may hold the address of an instruction (i.e. function pointer), it is no required to
[C]. A variable that stores address of other variable -> Correct. A pointer is a variable that stores the address of any other variable be it a value or another address.
[D]. All of the above -> Wrong as A and B are incorrect.

pointer is also variable it stores the addres of another variable and also stores addres of itself.
//
(i) int i,*p;
p=&i;
(ii) int *p;
p=&p;
//
both cases are possible i hope now u understand wt a pointer is

Ya its a variable holding adress of other variable as a content of it.

Cute answer Raju.

Normal variable means it stores the values directly. But if you want to change those values without touching those variables we are using pointers.

Pointer is a one type of variable it holds the address of the variable.

int a=5; // suppose a variable address is 100
int *p;

p=&a;// here p(pointer variable)holdes the address of the a variable.

Pointer is just and address holder of anather variable narmally.

But it is a very good concept of reusability. In c pointer use some signs also.

Its basic definition of pointer.

By using pointer one can access memory location directly

A pointer is used to store the address of another variable
