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

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.

References The answer and explanation are based on general knowledge and common safety practices for handling electrical appliances; specific documents or standards on Scripting and Programming Foundations are not applicable here.

Programming libraries offer a collection of pre-written code that developers can use to perform common tasks, which saves time and effort. This is because:

• B.  

   Libraries provide pre-coded functions and procedures, which means programmers don’t need to write code from scratch for tasks that are common across many programs. This reuse of code enhances efficiency and reduces the potential for errors in coding those tasks.

• E.  

   By using libraries, programmers can significantly improve their productivity. Since they are not spending time writing and testing code for tasks that the library already provides, they can focus on the unique aspects of their own projects.

• The benefits of using programming libraries are well-documented in software development literature. For instance, “Code Complete” by Steve McConnell discusses how libraries can improve programmer productivity. Additionally, “The Pragmatic Programmer” by Andrew Hunt and David Thomas emphasizes the importance of reusing code to increase efficiency and reduce errors.
