 The operator that is helpful in determining if an integer is a multiple of another integer is the modulus operator, represented by / in some programming languages and % in others. This operator returns the remainder of the division of one number by another. If the remainder is zero, it indicates that the first number is a multiple of the second. For example, 6 % 3 would return 0, confirming that 6 is a multiple of 3.

 To find an expression that evaluates to 14 when y = 13, let’s evaluate each option:

A. 11 + y % 5: The modulo operation (%) gives the remainder after division. For y = 13, 13 % 5 equals 3. Adding 11 to 3 results in 14, so this expression is correct.

B. 11 - y / 5.0: Dividing 13 by 5.0 gives 2.6. Subtracting 2.6 from 11 does not yield 14, so this expression is incorrect.

C. (11 + y) % 5: Adding 11 to 13 results in 24. Taking the modulo of 24 with 5 gives 4, which is not equal to 14. Therefore, this expression is incorrect.

D. 11.0 - y / 5: Dividing 13 by 5 gives 2.6. Subtracting 2.6 from 11.0 does not yield 14, so this expression is incorrect.

The correct expression is A. 11 + y % 5.

The language described in the question exhibits characteristics of an interpreted, object-oriented, and dynamic language. Here’s why these terms apply:

Interpreted: The program can run on various operating systems without re-compilation, which is a trait of interpreted languages. Interpreted languages are executed line by line by an interpreter at runtime, rather than being compiled into machine code beforehand123.

Object-oriented: The use of concepts like information hiding, data abstraction, encapsulation, polymorphism, and inheritance are hallmarks of object-oriented programming (OOP). OOP languages are designed around objects and classes, which allow for modular, reusable, and organized code456.

Dynamic: Variables in the program do not need to have their types declared ahead of time, indicating dynamic typing. In dynamically typed languages, type checking is performed at runtime, and variables can be assigned to different types of data over their lifetime7891011.

Programming libraries are collections of pre-written code that developers can use to optimize tasks and solve common problems efficiently. By using a library, developers don’t have to write everything from scratch, which saves time and reduces the potential for errors. Libraries can provide solutions for user authentication, data visualization, animations, networking, and more, allowing developers to focus on the unique aspects of their projects rather than reinventing the wheel123.

Comprehensive and Detailed Explanation From Exact Extract:

The tasks described involve creating a technical plan (listing objects and functions) and coding (writing the objects). According to foundational programming principles and Agile methodologies, these correspond to the design phase (planning the structure) and the implementation phase (coding).

Agile Phases Analysis:

Analysis: Defines requirements (e.g., “the game must support players and moves”).

Design: Specifies technical components (e.g., objects like Player, Board, and functions like makeMove()).

Implementation: Writes the code for the specified components.

Testing: Verifies the code works as intended.

Tasks Breakdown:

Creating a list of objects and functions: This is a design task, as it involves planning the program’s structure (e.g., class diagrams or function signatures).

Writing the code for each object: This is an implementation task, as it involves coding the objects (e.g., implementing the Player class).

Option A: "Analysis and design." This is incorrect. Analysis defines high-level requirements, not the specific objects and functions, which are part of design.

Option B: "Design and implementation." This is correct. Designing the list of objects and functions occurs in the design phase, and writing their code occurs in the implementation phase.

Option C: "Analysis and implementation." This is incorrect. Analysis does not involve listing technical components like objects and functions.

Option D: "Design and testing." This is incorrect. Testing verifies the coded objects, not the act of creating their list or writing their code.

Comprehensive and Detailed Explanation From Exact Extract:

An interpreted language is executed directly by an interpreter, which reads and executes the source code line by line without requiring a separate compilation step. According to foundational programming principles, this allows for flexibility, such as running code interactively or one statement at a time.

Option A: "Generates syntax errors during compilation." This is incorrect. Interpreted languages (e.g., Python, JavaScript) do not undergo a compilation phase. Syntax errors are detected during execution by the interpreter, not during a compilation step.

Option B: "Can be run by a user one statement at a time." This is correct. Interpreted languages often support interactive execution, where users can input and execute code one statement at a time (e.g., in Python’s REPL or JavaScript’s browser console). This is a hallmark of interpreters.

Option C: "Has a programmer writing machine code." This is incorrect. No high-level programming language, interpreted or compiled, requires programmers to write machine code. Interpreted languages use high-level source code executed by an interpreter.

Option D: "Is restricted to running on one machine." This is incorrect. Interpreted languages are typically portable across machines, as long as the interpreter is available (e.g., Python runs on Windows, macOS, and Linux with the same source code).

To find the rightmost digit of an integer q = 7777, we need the units digit (i.e., 7). According to foundational programming principles, the modulo operator (%) with 10 isolates the rightmost digit of a number.

Option A: "10 % q."

Compute: 10 % 7777 = 10 (since 10 ÷ 7777 has a remainder of 10).

Result: 10 ≠ 7. Incorrect.

Option B: "q % 10."

Compute: 7777 % 10 = 7 (remainder of 7777 ÷ 10, isolating the units digit).

Result: 7 = rightmost digit. Correct.

Option C: "q / 10000."

Compute: 7777 / 10000 = 0.7777 (floating-point division).

Result: 0.7777 ≠ 7. Incorrect.

Option D: "q % 10000."

Compute: 7777 % 10000 = 7777 (since 7777 < 10000).

Result: 7777 ≠ 7. Incorrect.

Comprehensive and Detailed Explanation From Exact Extract:

Object-oriented programming (OOP) languages are distinguished by their use of objects, which encapsulate data and behavior, and support features like inheritance, polymorphism, and encapsulation. According to foundational programming principles (e.g., Certiport Scripting and Programming Foundations Study Guide), this object-based approach is unique to OOP and not inherent to procedural or functional paradigms.

Option A: "The language is optimized for recursive programming." This is incorrect. Recursion is a technique supported by many languages across paradigms, including procedural (e.g., C), functional (e.g., Haskell), and object-oriented (e.g., Java). It is not unique to OOP.

Option B: "The language is based on the concept of modular programming and the calling of a subroutine." This is incorrect. Modular programming and subroutines (functions or procedures) are central to procedural languages (e.g., C) and also supported in functional languages. While OOP languages support modularity, this is not their distinguishing feature.

Option C: "The language treats programs as evaluating mathematical functions." This is incorrect. This describes functional programming languages (e.g., Haskell, Lisp), which emphasize immutability and function evaluation, not OOP.

Option D: "The language supports decomposing a program into objects that interact with one another." This is correct. OOP languages (e.g., Java, C++, Python) are characterized by organizing code into objects that encapsulate data and methods, interacting through messages or method calls. This is not a feature of procedural (e.g., C) or functional (e.g., Scheme) languages, which focus on procedures or functions, respectively.
