Scripting-and-Programming-Foundations Exam Dumps - WGU NDE Questions and Answers

In the Waterfall approach to software development, the phase that defines and specifies how to build a program is the Design phase. This phase follows the initial Analysis phase, where the requirements are gathered, and precedes the Implementation phase, where the actual coding takes place. During the Design phase, the software’s architecture, components, interfaces, and data are methodically planned out. This phase translates the requirements into a blueprint for constructing the software, ensuring that the final product will meet the specified needs.

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.

A string is a data type used to store sequences of characters, such as text or words. According to foundational programming principles (e.g., Certiport Scripting and Programming Foundations Study Guide), strings are ideal for textual data but not for numerical or boolean values, which have specific data types (e.g., integers, floats, booleans).

Option A: "A true/false indication of whether a number is composite." This is incorrect. A true/false value is a boolean, not a string. In most languages (e.g., Python’s True/False, C’s 0/1), booleans are a distinct type.

Option B: "A positive number between 2 and 3." This is incorrect. A number between 2 and 3 (e.g., 2.5) is a floating-point value, not a string. Strings could represent numbers as text (e.g., "2.5"), but this is not the primary use.

Option C: "The word 'positive'." This is correct. The word "positive" is a sequence of characters, perfectly suited for a string data type (e.g., char[] in C, str in Python).

Option D: "A positive whole number." This is incorrect. Whole numbers are stored as integers (e.g., int in C or Python), not strings, unless represented as text (e.g., "123"), which is not implied here.

Safety and proper procedure are paramount when replacing a light bulb to avoid any electrical hazards or injuries. First, always ensure the lamp is turned off to prevent electrical shock. Next, carefully unscrew the broken or burnt-out bulb from the socket; it might be hot, so caution is advised. After removing the old bulb, screw in the new working bulb securely but without overtightening to avoid damaging the bulb or socket. Finally, turn the lamp on to verify that the new bulb is functioning properly.

The provided code defines a function named F that takes two strings si and l2 as input. However, there seems to be a typo in the variable names (si instead of sign and l2 instead of horse).

Inside the function:

Put sl to output: This line likely has a typo as well. It's intended to print the input strings, but there's a missing space between si and l2. Assuming the correction, this line would concatenate si and l2 with a space and print it.

Put 2 to output: This line would print the number 2.

and : This line by itself wouldn't print anything.

Calling the Function Twice:

If F(sign, horse) is called twice:

First Call:

It would likely print "sign horse" (assuming the space is added between si and l2) followed by "2".

Second Call:

It would likely print "sign horse" (assuming the space is added between si and l2) followed by "2" again.

Total Output:

Therefore, the total output when F(sign, horse) is called twice would be:

sign horse 2

sign horse 2

 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.

Object-oriented languages are defined by their use of objects, which combine data (attributes) and operations (methods) to model real-world entities. According to foundational programming principles, this encapsulation of data and behavior is a hallmark of OOP languages.

Option A: "Supports creating programs as items that have data plus operations." This is correct. OOP languages (e.g., C++, Java, Python) organize programs into objects, where each object contains data (fields or attributes) and operations (methods). For example, a Car object might have data like speed and methods like accelerate().

Option B: "Supports creating programs as a set of functions." This is incorrect. This describes functional or procedural languages (e.g., C, Haskell), where programs are structured as functions or procedures, not objects.

Option C: "Requires a compiler to translate to machine code." This is incorrect. Not all OOP languages require compilation to machine code (e.g., Python is interpreted). Compilation is a characteristic of some languages (e.g., C++, Java), not a defining feature of OOP.

Option D: "Can be run on any machine that has an interpreter." This is incorrect. While some OOP languages (e.g., Python) are interpreted, others (e.g., C++) are compiled. Interpretability is not specific to OOP.

Comprehensive and Detailed Explanation From Exact Extract:

A compiled programming language is one where the source code is translated into machine code (or an intermediate form) by a compiler before execution. According to foundational programming principles (e.g., Certiport Scripting and Programming Foundations Study Guide), this process results in an executable file that can run independently of the compiler.

Option A: "The program usually runs slower than an interpreted language." This is incorrect. Compiled languages (e.g., C, C++) typically produce machine code that runs faster than interpreted languages (e.g., Python), as the translation to machine code is done beforehand, avoiding runtime interpretation overhead.

Option B: "The code runs directly one statement at a time by another program called a compiler." This is incorrect. A compiler translates the entire program into machine code before execution, not one statement at a time. Running code one statement at a time is characteristic of an interpreter, not a compiler.

Option C: "The code must be compiled into machine code in the form of an executable file before execution." This is correct. In compiled languages like C or Java (which compiles to bytecode), the source code is translated into machine code or an intermediate form (e.g., .exe or .class files) that can be executed directly by the machine or a virtual machine.

Option D: "The code does not require being translated into machine code but can be run by a separate program called a compiler." This is incorrect. A compiler’s role is to translate code into machine code. Running code without translation describes an interpreted language, and the term “compiler” is misused here.

The code snippet not (g != S) contains two types of operators:

Equality Operator (!=): The expression g != S checks whether the value of g is not equal to the value of S. The != operator is used for comparison and returns True if the values are different, otherwise False.

Logical Operator (not): The not operator is a logical negation operator. It inverts the truth value of a Boolean expression. In this case, not (g != S) evaluates to True if g is equal to S, and False otherwise.

Therefore, the combination of these two operators results in the overall expression not (g != S).

A sorting algorithm is correct if it consistently produces a sorted output (e.g., ascending order: [6, 8, 10] for input [10, 6, 8]). According to foundational programming principles, if an algorithm fails to sort any input correctly, it is considered incorrect for the general case.

Analysis:

Input: [10, 6, 8].

Output: [6, 10, 8].

Correct sorted output: [6, 8, 10] (ascending).

The algorithm’s output [6, 10, 8] is not sorted, as 10 > 8.

Option A: "The algorithm is incorrect." This is correct. Since the algorithm fails to sort [10, 6, 8] correctly, it is not a valid sorting algorithm for arbitrary inputs. A single failure proves incorrectness for the general case.

Option B: "The algorithm only works for [10, 6, 8]." This is incorrect. The algorithm does not “work” for [10, 6, 8], as it produces an incorrect output.

Option C: "The algorithm’s correctness is unknown." This is incorrect. The given example demonstrates incorrectness, so the algorithm is known to be incorrect.

Option D: "The algorithm is correct." This is incorrect. The algorithm fails to sort the given input correctly.
