Programming Problem 4 in Chapter 10 asked you to write a second educational program for learning about geologic time. Rewrite that program using a class to implement an ADT representing a period of geologic time. If you did Programming Warm-Up Exercises 7 through 12, then you’ve already done some of this work. The ADT in those exercises needs to be enhanced with a constructor that takes a string as an argument and converts the string to the corresponding Period value (the constructor should work with any style of capitalization of the period names). In this program, the computer picks a date in geologic time and presents it to the student. The student guesses which period corresponds to the date. The student is allowed to continue guessing until he or she gets the right answer. The program then asks the user whether he or she wants to try again, and repeats the process if the answer is “yes.” You also may want to write a function that returns the period for a given date; however, this function does not need to be part of the class.

REF PRB:

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.

REF PRB:

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.
