Programming Problems 3 and 4 in Chapter 10 asked you to develop educational programs for teaching the periods of geologic time. Now that you know how to write classes, you can turn the Period ADT into a class. Write a specification file for class Period, which has a private field that’s an enumeration type, representing the names of the periods. Class Period should have functions that return the period as a string, that return the period as an int, that return the starting date of the period, and that increment the period to the next most recent period (if the period is already NEOGENE, the increment operation should do nothing). It should have a default constructor that sets the period to PRECAMBRIAN, and a constructor with a parameter of the enumeration type to allow the user to create a Period object containing any period. For ease of reference, the table of the time periods is repeated here from Chapter 10. Be sure to use appropriate documenting comments.

REF PRBS:

You are taking a geology class, and the professor wants you to write a program to help students learn the periods of geologic time. The program should let the user enter a range of prehistoric dates (in millions of years), and then output the periods that are included in that range. Each time this output is done, the user is asked if he or she wants to continue. The goal of the exercise is for the student to try to figure out when each period began, so that he or she can make a chart of geologic time.

Within the program, represent the periods with an enumeration type made up of their names. You will probably want to create a function that determines the period corresponding to a date, and another function that returns the string corresponding to each identifier in the enumeration. Then you can use a For loop to output the series of periods in the range. The periods of geologic time are given here:

Use functional decomposition to solve this problem. Be sure to use good coding style and documenting comments. The prompts and error messages that are output should be clear and informative.

The educational program that you wrote for Problem 3 was a big success. Now the geology professor wants you to write another program to help teach geologic time. In this program, the computer picks a date in geologic time and presents it to the student. The student then guesses which period corresponds to the date. The student is allowed to continue guessing until he or she gets the right answer. Then the program asks the student whether he or she wants to try again, and repeats the process if the answer is “yes.” To solve this problem, you should again use an enumeration type consisting of the names of the periods. In this case, you’ll probably want to make a function that returns the period corresponding to a string containing the name of a period (the program should work with any style of capitalization of the names). You also may want a function that returns the period for a given date. Use functional design to solve this problem. Be sure to use good coding style and include helpful documenting comments. The prompts and error messages that are output should be clear and informative. You may want to add some interest to the program by keeping track of the number of guesses taken by the user, and offering differing levels of praise and encouragement depending on how well the user is doing.
