Write a program that creates the structure shown in Sample solution.

$2.$ It then reads data into a$,$ b$,$ and c using the pointers p$,$ q$,$ and r$.$

$3.$ After the data has been read, the program reassigns the pointers so that p points to

c$,$ q points to a$,$ and r points to b$.$

$4.$ After making the reassignments, the program prints the variables using the

pointers.

$5.$ For each variable, print both its contents and its address.
