  True
• What is the primary goal of optimizing code efficiency?

  Reduce resource usage
• Error messages should help users understand the issue.
• What is the first step in refining a program effectively?

  Identify areas for improvement
• Ensuring the code is easy to understand falls under the category of clarity.
• The 'try-except' block is used to handle unexpected errors in code.


  True
• Match the debugging tool with its supported languages:

  Visual Studio Debugger ↔️ C++, C#, Python

  Eclipse Debugger ↔️ Java, C++, Python

  PyCharm Debugger ↔️ Python

  GDB (GNU Debugger) ↔️ C, C++, Assembly
• What is the purpose of analyzing call stacks in debugging?

  Trace program execution
• The PyCharm Debugger includes features like code completion and variable inspection.


  True
• The `try-except` block allows developers to catch and handle exceptions.
• The `finally` block ensures code executes regardless of whether an exception occurs.

  True
• Informative error messages help users understand the issue causing the error.


  True
• The `try-except` block is used to catch and handle exceptions
• The `finally` keyword ensures that code executes regardless of exceptions.


  True
• Match the key aspects of code clarity with their descriptions:

  Meaningful variable names ↔️ Descriptive and clear names

  Comments ↔️ Explain code logic

  Proper indentation ↔️ Improves readability
• Avoiding redundant calculations is essential for code efficiency.

  True
• Debugging tools help developers isolate and fix problems in their code
• The try-except block in Python is used to catch and handle exceptions.

  True
• What does the raise keyword do in error handling?

  Create and throw exceptions
• In the example \try:\file = open("example.txt", "r")\finally:\file.close()</latex>, what does the finally block ensure?

  File is closed
• What are the two key areas to focus on when refactoring code for clarity and efficiency?

  Code Clarity and Efficiency
• Proper code indentation is crucial for improving code readability and clarity.

  True
• What is the primary goal of unit testing in programming?

  Ensure individual components work
• What does integration testing focus on in programming?

  How components work together
• Unit testing ensures individual components of a program work as expected
• Integration testing verifies how different components of a program work together.


  True
• Integration testing ensures the overall system functions correctly.

  True
• A change log is a record of modifications made to the code over time.

  True
• Using meaningful variable and function names improves code readability
