/* 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
