Array of pointers

Array of pointers:-

            A pointer variable can store address of another variable whereas the array of pointers can store addresses of array elements. The pointer array can be declared as follows:

Syntax:-

            Datatype *variable[size];

Eg.,

            int *ap[10];

i.e., it indicates that ap is a pointer array which can store addresses of 10 elements which are of integer datatype.

Ø  A Program to print elements of an array and their corresponding addresses.

#include<stdio.h>

   #include<conio.h>

            void main( )

                        {

int a[5]={1,2,3,4,5},*ap[5],i;

for(i=0;i<5;i++)

ap[i]=a+i;

printf(“the elements are”);

for(i=0;i<5;i++)

printf(“%d is at %u\n”,*ap[i],ap[i]);

getch( );

                        }
