CS 111: Program 2 main content

Based on Programming Challenge #5: Driver's License Exam Class on page 538 of your textbook.

Write a program to

• read in five multiple choice questions from a file (same as Lab 2)
• display each question, one at a time, to the user
• read the user's answer
• grade the exam and
  • display the total number of questions they got right
  • display whether they passed the exam (Need at least 60% of the questions right)
  • display the question numbers for the questions the user got wrong

Hint: store the user's answers in an array of char.

Sample Session

Design your own console-based user interface. Make it user-friendly and easy to follow

Programming Style Requirements

• Read through the Java Programming Style Guide for expectations.
• Begin every java file with the standard file header
• Use jGRASP's Control Structure Diagram (CSD) for indentation.
• Print your source code with CSD and line numbers.

What to turn in

1. Source program printouts stapled together with file header comments on all printouts
2. Be sure your project is saved in your u:\Program2\ folder
3. The assignment is due at the start of lab 3. You program must compile and produce output for you to receive any credit.
   • You are allowed one late programming assignment for the quarter.

Grading Criteria

50 points maximum

• 10 points - User Interface
  • Input prompts and output format are easy to follow (3)
  • Input Validation: only accept letters A, B, C, and D as answers (3)
  • Graded results are clear and easy to understand (4)
  • Spelling, capitalization, and grammar are correct (-1 per error)
  • Spacing and alignment are correct (-1 per error)
• 25 points - Output Correctness
  • The program asks a question and reads the test taker's response (10)
  • The program calculates and displays the number of questions answered correctly (5)
  • The program calculates and displays whether the test taker passed the exam (5)
  • The program stores and displays the question numbers that were answered incorrectly (5)
• 5 points - Object Oriented Design
  • The program is subdivided into appropriate classes and methods
    • Re-use your MultipleChoiceQuestion class
    • Keep methods under 25 lines of code (LOC) in length and do one thing per method
    • Use private helper methods whenever appropriate
• 5 points - Programming Style
  • Program header comments are present and complete. All files need header comments (2)
  • Single-line comments are present, helpful, and sufficient (2)
    • Skip a blank line before every single-line comment
    • Align the comment with the code
    • Generally one single-line comment is needed for every four to six lines of code
  • Naming conventions, alignment, and indentation are important. Read through the Java Style Guide for CS 111 expectations (1)
• 5 points - Creation and printout of the jGRASP Project files
  • Project U:\Program2\ created correctly in your network cs111 account and project files saved correctly in the project folder (2)
  • Source printouts submitted correctly
    • Avoid line wrap in your source printout
    • Print both files with line numbers and CSD showing
