Explain why high-level languages are considered easier for programming compared to machine language.

Multiple Choice

What is the main purpose of an Editor, Interpreter, and Compiler in programming?

• To execute code line by line

• To translate code into machine language

• To write and edit code

• To highlight syntax errors

Multiple Choice

Compare procedural programming vs OOP in terms of their basic idea, focus, data handling, structure, reusability, security, examples of use, program flow, languages, complexity level, maintainability, and real-world modeling.

• Procedural programming is built using procedures/functions, while OOP is built using objects that contain data + behavior.

• Procedural programming focuses on tasks, while OOP focuses on objects.

• Data handling in procedural programming is separate from functions, while in OOP, data is inside objects protected by classes.

• Procedural programming has a linear structure, while OOP has a modular structure based on classes and objects.

Multiple Choice

What is the purpose of pseudocode in algorithm development?

• To write code directly

• To describe algorithms in plain English

• To create flowcharts

• To model system interactions

Multiple Choice

What are the multiple way algorithms can be represented?

• Natural language, like English

• Visually, using flowcharts

Multiple Choice

How would you modify line 3 so that the loop stops when both dice are equal to 3?

• when (die1 <= 3 && die2 <= 3) {

• when (die1 == 3 || die2 == 3) {

• when (die1 == 3 && die2 == 3) {

• when ((die1 + die2) == 3) {

Multiple Choice

What are the three main steps involved in the Merge Sort algorithm?

• Divide the list into smaller pieces

• Sort each piece

• Merge pieces back in order

• Combine all pieces into one

Multiple Select
