1. Modify the above program such that a function is used to input values to the members and another function to display the time.
2. Design a function update that would accept the data structure designed in Exercise 12.1
and increments time by one second and returns the new time. (If the increment results in
60 seconds, then the second member is set to zero and the minute member is incremented
by one. Then, if the result is 60 minutes, the minute member is set to zero and the hour
member is incremented by one. Finally when the hour becomes 24, it is set to zero.)
