Fall 2024 CS 18000 Midterm Exam 1

Exam Instructions

• Total of 75 points; includes fill in the blank, short answer, multiple choice, and coding questions.
• Submissions should follow academic integrity guidelines; no unauthorized help or resources.
• Bring only writing utensil and eraser; no notes or electronic devices allowed.
• All answers must be written in designated boxes; illegible handwriting will receive a zero.

Code Tasks Overview

• Use given variable types and initializations to write concise code.
• Code tasks include printing formatted strings, using loops, declaring booleans, and initializing integers.
• Tasks also require constructing classes and methods for banking-related functionalities, including deposit methods and prime factorization.

Important Code Concepts

• Printf Formatting: Use printf for formatted output; helpful for displaying numbers and strings.
• Looping: Understand how to implement looping structures, such as for loops that utilize Fibonacci sequences.
• String Manipulation: Utilize substring methods for extracting parts of strings.
• Boolean Logic: Use boolean flags to determine the state of variables, especially in context of account management.
• Class Design: Be familiar with creating constructors and methods within classes, especially managing multiple types of accounts.

Class AccountManager

• Constructor Requirement: Must take username and account type to determine account status.
• Boolean Variables: Must be set based on whether accounts (checking, savings, loan) are active according to specified types.
• Deposits: Implement deposits with conditions based on account type and balance checks.

Infinite Menu Implementation

• Input Handling: Continuously prompt for username and number of posts, validating entries.
• Ensure to provide feedback for invalid entries and use predefined messages for user interaction.
• Posts are displayed based on returned values categorized by their division properties.

Mathematical Operations

• Factorial and prime factorization must return string representations formatted correctly with specific separators.
• Solve specific computational problems, such as identifying numbers that equal the sum of the factorials of their digits.

Miscellaneous Knowledge

• Understand binary representations, signed values, and their maximum and minimum size calculated by binary length.
• Recognize specific cases favoring the use of do-while loops in programming.
• Convert integers to binary in two's complement representation as part of exam tasks.

Final Notes

• Prepare to answer both theoretical questions around code behavior and practical coding challenges.
• Familiarize yourself with best practices for writing clean, functional code within the time constraints of the exam.
