C program to illustrate the usage of pointers

Write a C program to illustrate the usage of pointers and its accessibility.

  #include <stdio.h>
  int main() {
        int val, *data;

        /* get the input data from the user */
        printf("Enter the value for val:");
        scanf("%d", &val);

        /* store the address of the variable 'val' */
        data = &val;

        /* print the outputs */
        printf("val            : %d\n", val);
        printf("Address of val : 0x%x\n", (int)&val);
        printf("data           : 0x%x\n", (int)data);
        printf("*data          : %d\n", *data);
        printf("Address of data: 0x%x\n", (int)&data);
        return 0;
  }

  Output:

  jp@jp-VirtualBox:~/$ ./a.out
  Enter the value for val:10000
  val            : 10000
  Address of val : 0xbfdafd5c
  data           : 0xbfdafd5c
  *data          : 10000
  Address of data: 0xbfdafd58
