In the pointer array, the array elements is the pointer.

#include <stdio.h>

main(){
    int *a[5];

    int i1=4,i2=3,i3=2,i4=1,i5=0;
    a[0]=&i1;
    a[1]=&i2;
    a[2]=&i3;
    a[3]=&i4;
    a[4]=&i5;

    printf("Address        Address in array         Value\n");

    int j;
    for(j=0;j<5;j++)
    {
        printf("%16u           %16u                 %d\n",
        a[j],a[j],a[j]);
    }

    printf("using pointer\n");
    int *b;
    b = a;
    for( j=0;j<5;j++)
    {
        printf("value of elements   %d %16lu\n",*b,*b,b);
        b++;

    }
