    for (int i = 0; i < 4; i++)

    {

        scanf("%d", arr + i);

    }

    for (int i = 0; i < 4; i++)

    {

        printf("Value at [%d] : %d ",i, *(arr + i));

        printf("Pointer at [%d] : %d \n",i, (arr + i));

    }

    char ch = 'A';

    printf("\n For Char %c : Pointer is %d ", ch, &ch);
