Program Specifications

General

  1. Note that you must complete these programs either by yourself or by working with one other student of this class following the rules of Pair Programming for Homework Assignments.
  2. Remember to follow all the style rules from the last assignments as well as the new rules we covered including:
    1. No magic numbers (See: No Magic Numbers)
    2. Indentation in while statements and placement of curly braces (See: Indentation)
  3. Submit your files to Blackboard as explained in the section of this document: What to Turn In.

Working with Time

  1. Complete Exercise P3.11 on page 128 of the textbook.
  2. Add a while statement that allows the user to repeat the program by entering a "y" (without the quotes).
  3. The name of the source code file for this program must be comptime.cpp and all your code must be in this file.

    Be careful of the spelling, including capitalization, as you will lose points for a misspelled name.

  4. Your program must operate like this: 
    Enter two times and I will print which comes first.

Enter the first time in military format (like, 1930): 1930
Enter the second time: 1700
1700 1930
Run again? (y/n) y

Enter the first time in military format (like, 1930): 0830
Enter the second time: 1930
830 1930
Run again? (y/n) y

Enter the first time in military format (like, 1930): 1930
Enter the second time: 1930
1930 == 1930
Run again? (y/n) n

Days in a Month

  1. Complete Exercise P3.23 on page 131 of the textbook.
  2. Add a while statement that allows the user to repeat the program by entering a "y" (without the quotes).
  3. The name of the source code file for this program must be monthdays.cpp and all your code must be in this file.

    Be careful of the spelling, including capitalization, as you will lose points for a misspelled name.

  4. Your program must operate like this: 
    I will print the number of days in a month.

Enter the month (1-12): 9
30 days
Run again? (y/n) y

Enter the month (1-12): 2
28 or 29 days
Run again? (y/n) y

Enter the month (1-12): 1
31 days
Run again? (y/n) n
Hint: Thirty days hath September

Working with Numbers in the Electromagnetic Spectrum

  1. Complete Exercise P3.6 on page 127 of the textbook.
  2. Add a while statement that allows the user to repeat the program by entering a "y" (without the quotes).
  3. The name of the source code file for this program must be spectrum.cpp and all your code must be in this file.

    Be careful of the spelling, including capitalization, as you will lose points for a misspelled name.

  4. Your program must operate like this: 
    Enter a wavelength and I will report the type of
the electromagnetic spectrum.

Enter a wavelength in meters: .001
Microwaves
Run again? (y/n) y

Enter a wavelength in meters: 4e-7
Visible light
Run again? (y/n) n
Hint: Here are the first few numbers in exponential and fixed notation. See lesson 4.1.2 for more information.

Scientific Exponential Fixed
10-1 1e-1 0.1
10-3 1e-3 0.001
7 x 10-7 7e-7 0.0000007

Extra Credit

The following are worth extra credit points:

  1. Complete the assignment using pair programming. (1 point)
  2. Complete Exercise P3.12 on page 128 of the textbook. The name of the source code file for this program must be seasons.cpp. (2 points)

    Your program must operate like this:

    I will print the seasons.

Enter the month (1-12): 3
Enter the day (1-31): 20
The season is Winter
Run again? (y/n) y

Enter the month (1-12): 3
Enter the day (1-31): 21
The season is Spring
Run again? (y/n) n

Make certain that your README.txt file describes any extra credit attempted.

Tutorial Exercises

To prepare for the next lesson, complete the following exercises.

  1. Type the program invtable.cpp from the textbook on page 149 into a text editor, and then compile and run the program. Submit your working source code file to Blackboard for grading using the file name invtable.cpp.
  2. Complete the Tutorial Exercises in CodeLab 4 before the specified due date. Refer to the assigned reading for the next lesson to help you understand the problems. Also, you can use the online lecture notes for more information as the notes become available. You can look at solutions if you miss your first attempt by clicking the "Solution" tab.

Grading Criteria

The instructor will evaluate your assignment using the following criteria. Each criteria represents a specific achievement of your assignment and has a scoring guide. The scoring guide explains the possible scores you can receive.

Some scoring guides have a list of indicators. These indicators are a sign of meeting, or a symptom of not meeting, the specific criterion. Note that a single indicator may not always be reliable or appropriate in a given context. However, as a group, they show the condition of meeting the criterion.

For information on grading policies, including interpretation of scores, see the course information page.
