Problem Statement

Figure 9.4 shows three memory locations and values stored in them. Write a program to declare variables that implement the relationship shown. How will you print the values and addresses shown in the figure? On which machine the program should be executed to get such addresses? Figure 9.4: value: 3.14, memory_address: 7fff9489c79c value: 7fff9489c7a0, memory_address: 7fff4fd134b8 value: 7fff9489c79c, memory_address: 7fff9489c7a0

    printf("Location 1 (Variable a):\n");
    printf("Value: %g\n", a);
    printf("Address: %p\n", (void *)&a);
    printf("------------------------------\n");

    printf("Location 3 (Variable c: float *):\n");
    printf("Value (Address stored): %p\n", (void *)c);
    printf("Address of c itself: %p\n", (void *)&c);
    printf("Value pointed to (*c): %g\n", *c);
    printf("------------------------------\n");

    printf("Location 2 (Variable b: float **):\n");
    printf("Value (Address stored): %p\n", (void *)b);
    printf("Address of b itself: %p\n", (void *)&b);
    printf("Value pointed to (*b): %p\n", (void *)*b);
    printf("Value pointed to (**b): %g\n", **b);
    printf("------------------------------\n");
