FCP Programming Fundamentals 1 — Questions and Answers
Question 1: What is the purpose of version control in software development?
- To track changes, enable collaboration, and maintain code history (Correct answer)
- To backup files to an external drive
- To count the number of lines of code written
- To monitor developer productivity
Correct answer: To track changes, enable collaboration, and maintain code history
Version control systems track all code changes, enabling team collaboration and providing a complete history of modifications.
Question 2: What is the DRY principle in programming?
- Dont Repeat Yourself — avoid code duplication (Correct answer)
- Document, Review, Yield
- Delete Redundant Yields
- Debug and Run Yearly
Correct answer: Dont Repeat Yourself — avoid code duplication
DRY means every piece of knowledge should have a single, unambiguous representation in a system, reducing redundancy.
Question 3: What is the difference between compiled and interpreted languages?
- Compiled code is translated to machine code before execution; interpreted code is translated line by line during execution (Correct answer)
- There is no practical difference
- Compiled languages are always faster
- Interpreted languages cannot be used for web development
Correct answer: Compiled code is translated to machine code before execution; interpreted code is translated line by line during execution
Compiled languages are fully translated before execution, while interpreted languages are translated during runtime.
Question 4: What is the purpose of unit testing?
- To verify that individual components of code work correctly in isolation (Correct answer)
- To test the entire application at once
- To check network connectivity
- To measure code performance only
Correct answer: To verify that individual components of code work correctly in isolation
Unit tests verify individual components in isolation, catching bugs early and making code more maintainable.
Question 5: What is an algorithm?
- A step-by-step procedure for solving a problem or accomplishing a task (Correct answer)
- A type of programming language
- A hardware component of a computer
- A network protocol
Correct answer: A step-by-step procedure for solving a problem or accomplishing a task
An algorithm is a finite sequence of well-defined instructions for solving a specific problem or performing a computation.
Question 6: What is the purpose of code review?
- To identify bugs, improve code quality, and share knowledge among team members (Correct answer)
- To slow down the development process
- To assign blame for errors
- To satisfy management reporting requirements only
Correct answer: To identify bugs, improve code quality, and share knowledge among team members
Code review improves quality through peer examination, catches defects early, and spreads knowledge across the team.
