What are Pointers?

A pointer is a variable whose value is the address of another variable, i.e., direct address of the memory location. Like any variable or constant, you must declare a pointer before using it to store any variable address.

 
 

The general form of a pointer variable declaration is −

  • type *var-name;

Here, type is the pointer’s base type; it must be a valid C data type and var-name is the name of the pointer variable.

The asterisk * used to declare a pointer is the same asterisk used for multiplication. However, in this statement the asterisk is being used to designate a variable as a pointer.

 

The unary or monadic operator & gives the “address of a variable’”.

The indirection or dereference operator * gives the “contents of an object pointed to by a pointer”.

Below is the source code for C Program to display array with addresses using pointers which is successfully compiled and run on Windows System to produce desired output as shown below :

SOURCE CODE : :

/*  C Program to display array with addresses using pointers  */

#include<stdio.h>
#include<stdlib.h>
#define size 10
 
int main() 
{
   int a[3] = { 11, 22, 33 };
 
   printf("\n a[0] ,value=%d : address=%u", a[0], &a[0]);
   printf("\n a[1] ,value=%d : address=%u", a[1], &a[1]);
   printf("\n a[2] ,value=%d : address=%u", a[2], &a[2]);
 
   return (0);
}

Output : :

/*  C Program to display array with addresses using pointers  */

 a[0] ,value=11 : address=6356740
 a[1] ,value=22 : address=6356744
 a[2] ,value=33 : address=6356748

Process returned 0
