WGU Updated Scripting-and-Programming-Foundations Exam Questions and Answers by ria

Interpreted languages are designed to be executed one statement at a time by an interpreter. This allows for immediate execution and feedback, which is useful for debugging and interactive use. Unlike compiled languages, interpreted languages do not generate machine code prior to execution, and they do not produce syntax errors during compilation because there is no compilation step. They are not restricted to one machine, as the interpreter can be implemented on various systems, and they do not require the programmer to write machine code.

References:

• The characteristics of interpreted languages are discussed in educational resources such as “Programming Language Pragmatics” by Michael L. Scott and “The Art of Computer Programming” by Donald E. Knuth. These texts explain the execution model of interpreted languages and contrast it with that of compiled languages.

• E. The programmer can improve productivity by using libraries.
• F. Using a library prevents a programmer from having to code common tasks by hand.

 An algorithm is a set of step-by-step instructions for completing a task. In the context of buying a pair of shoes from a store, the first logical step would be to enter the store. This is because one cannot select a pair of shoes, bring them to the cashier, or pay for them without first entering the store. The steps should follow a logical sequence based on the dependencies of each action:

• Enter the store - This is the initial step as it allows access to the shoes available for purchase.
• Select the pair of shoes - Once inside, the next step is to choose the desired pair of shoes.
• Bring the shoes to the cashier - After selection, the shoes are taken to the cashier for payment.
• Pay for the shoes - The final step is the transaction to exchange money for the shoes.

References:

• The concept of algorithms and their properties can be found in computer science and programming literature, such as “Introduction to Algorithms” by Cormen, Leiserson, Rivest, and Stein.
• The logical ordering of steps in a process is a fundamental aspect of algorithm design, which is covered in foundational programming and scripting courses.

• Measure and mark the lumber cuts: This step involves measuring and marking the specific cuts required for the picnic table. It ensures that the lumber pieces are appropriately sized for assembly.
• Determine the needed materials: Before purchasing materials, it’s essential to determine what is required. This step involves creating a list of necessary items such as lumber, screws, paint, etc.
• Buy the needed materials: Once the materials list is ready, proceed to purchase them. This step ensures that you have all the necessary supplies before starting the construction.
• Cut the lumber to the proper dimensions: With the materials on hand, cut the lumber according to the measurements marked in step 1. This ensures that the pieces fit together correctly during assembly.
• Assemble the pieces and paint: Finally, assemble the cut lumber pieces to create the picnic table. After assembly, apply paint or finish as desired.
