Scripting-and-Programming-Foundations Dumps with Practice Exam Questions Answers

One of the fundamental characteristics of object-oriented programming (OOP) is the concept of decomposing a program into objects that interact with one another1. This is distinct from procedural and functional programming paradigms, which do not inherently structure programs as a collection of objects. In OOP, objects are instances of classes and contain both data (attributes) and code (methods). These objects encapsulate data and operations and can interact with each other through methods, allowing for concepts such as inheritance, polymorphism, and encapsulation12.

In contrast, procedural programming is characterized by a focus on procedures or routines to perform tasks, and functional programming treats computation as the evaluation of mathematical functions without side effects or state changes2. Neither paradigm organizes code around objects with encapsulated data and methods, which is a defining feature of OOP1.

Equality operators compare two values to determine if they are equal or not equal, returning a boolean result. According to foundational programming principles, common equality operators are == (equal to) and != (not equal to).

Option A: "-." This is incorrect. The subtraction operator (-) is an arithmetic operator, not an equality operator.

Option B: "==." This is correct. The equality operator (==) checks if two values are equal (e.g., 5 == 5 returns True).

Option C: "/." This is incorrect. The division operator (/) is an arithmetic operator, not an equality operator.

Option D: "not." This is incorrect. The not operator is a logical operator that negates a boolean value, not an equality operator.

Option E: "<=." This is incorrect. The less-than-or-equal-to operator (<=) is a relational (comparison) operator, not an equality operator.

Option F: "!=." This is correct. The not-equal-to operator (!=) checks if two values are not equal (e.g., 5 != 3 returns True).

Comprehensive and Detailed Explanation From Exact Extract:

The expression x - y * 2 involves subtraction and multiplication, evaluated according to operator precedence. According to foundational programming principles (e.g., C and Python standards), multiplication (*) has higher precedence than subtraction (-), so y * 2 is computed first.

Given: x = 12, y = 4.

Compute: y * 2 = 4 * 2 = 8.

Then: x - (y * 2) = 12 - 8 = 4.

Option A: "4." This is correct, as calculated above.

Option B: "6." This is incorrect. It might result from misinterpreting precedence (e.g., (x - y) * 2 = (12 - 4) * 2 = 16).

Option C: "8." This is incorrect. It might result from computing x - y = 12 - 4 = 8 and ignoring * 2.

Option D: "14." This is incorrect. It does not align with the expression’s evaluation.

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).

A compiled language is one where the source code is translated into machine code, which is a set of instructions that the computer’s processor can execute directly. This translation is done by a program called a compiler. Once the source code is compiled into an executable file, it can be run on the target machine without the need for the original source code or the compiler. This process differs from interpreted languages, where the code is executed one statement at a time by another program called an interpreter, and there is no intermediate executable file created.

Option A describes an interpreted language, not a compiled one. Option B refers to type safety, which is a feature of some programming languages but is not specific to compiled languages. Option C describes a script or an interpreted language, which can be executed immediately by an interpreter without compilation.
