1.1 Decomposition and abstraction

Which of the following best describes decomposition in problem-solving?

• Breaking down a complex problem into smaller, more manageable parts.

• Ignoring unnecessary details to focus on the main problem.

• Combining multiple problems into a single, large problem.

• Using specific details to solve a problem without simplification.

What is the main benefit of using abstraction in programming?

• It allows programmers to avoid writing any code.

• It helps to manage complexity by focusing on important details.

• It ensures that all details of a problem are considered.

• It makes programs run faster by removing unnecessary code.

How does decomposition improve problem-solving?

• By allowing problems to be solved without human intervention.

• By reducing the need for documentation.

• By making large problems easier to understand and solve.

• By eliminating the need for testing.

Which of the following is an example of abstraction in programming?

• Writing detailed comments for each line of code.

• Using a function to perform a calculation without knowing how it works internally.

• Combining multiple functions into a single program.

• Writing all code in a single block without breaking it into functions.

What is a subprogram in programming?

• A smaller program that runs independently of the main program.

• A section of code that can be reused multiple times within a program.

• A program that only runs when the main program fails.

• A graphical interface component.

Why is it beneficial to use subprograms in software development?

• Subprograms reduce the overall size of the program.

• They allow for code reuse and improve modularity.

• Subprograms automatically optimize the code for performance.

• They replace the need for a main program.

Which of the following is an advantage of decomposition?

• It ensures that every part of the problem is solved simultaneously.

• It allows different team members to work on separate parts of the problem.

• It eliminates the need for testing and debugging.

• It guarantees that the problem will be solved in one step.

How do subprograms help in managing large codebases?

• By preventing the need for debugging.

• By allowing for easier maintenance and updates.

• By automatically documenting the code.

• By combining all the code into a single function.

Which of the following best describes the relationship between decomposition and abstraction?

• Decomposition breaks down a problem, while abstraction hides unnecessary details.

• Decomposition hides unnecessary details, while abstraction breaks down a problem.

• Both decomposition and abstraction break down a problem.

• Both decomposition and abstraction hide unnecessary details.

Which of the following is a key advantage of modular programming?

• It eliminates the need for testing.

• It allows for parallel development by multiple team members.

• It ensures that the code is written in a single file.

• It makes the code harder to understand.
