xptr = &x; puts("Enter a new value for x"); scanf("%d",xptr);

printf ("The value of xptr is %X and x using this xptr is %d ",xptr,x); printf ("The address of x is %X ",&x);

printf("xptr is %X, *xptr is %d and &xptr is %X ",xptr,*xptr,&xptr);

puts("Ensure you understand what would happen if *xptr were used in scanf");
