Advanced Error Handling and Debugging Quiz

1. What does a segmentation fault typically indicate?

Invalid memory access in C or C++

Network connection failure

File system corruption

Insufficient disk space

2. In profiling, what metric helps identify performance bottlenecks?

Source lines of code

CPU time and memory usage per function

Number of variables

Comment density

3. What is the difference between a syntax error and a runtime error?

Syntax errors prevent compilation; runtime errors occur during execution

Runtime errors are more serious

Syntax errors only occur in interpreted languages

Both are equally easy to fix

4. Which log level should be used for informational messages about normal operations?

DEBUG

INFO

WARNING

ERROR

5. What does RAII stand for in C++?

Resource Allocation In Implementation

Resource Acquisition Is Initialization

Runtime Assertion In Instances

Recursive Algorithm Iteration Interface

6. In debugging, what is a race condition?

When two threads access shared data simultaneously without synchronization

When a program runs too fast

When debugging tools conflict

When the compiler optimizes too aggressively

7. What is the purpose of unit testing in error prevention?

To eliminate all debugging needs

To catch errors early before integration

To replace code reviews

To measure code speed

8. When should you use an unchecked exception in Java?

For all recoverable errors

For programming errors that represent bugs

Never; always use checked exceptions

Only in single-threaded applications

9. What is the primary advantage of using a debugger over print statements?

Debuggers are faster to write

You can inspect variables and step through code without recompilation

Debuggers prevent all errors

Print statements are obsolete

10. In exception handling, what is the purpose of a custom exception class?

To handle all errors in one place

To represent specific error conditions in your domain

To replace built-in exceptions

To improve program performance

11. What is the primary purpose of a stack trace in debugging?

Display memory allocation patterns

Show the sequence of function calls leading to an error

Measure program execution speed

Monitor variable values in real time

12. Which statement about breakpoints in debuggers is correct?

They permanently modify the code

They pause execution at specified lines for inspection

They can only be used in compiled languages

They eliminate the need for testing

13. What is the purpose of logging in production code?

To slow down execution for analysis

To record events and errors for troubleshooting after deployment

To replace exception handling entirely

To prevent all runtime errors

14. In Python, what exception is raised when dividing by zero?

ValueError

ZeroDivisionError

ArithmeticException

MathError

15. What is an assertion used for in programming?

To validate assumptions about program state during development

To permanently prevent invalid operations

To replace all error handling

To optimize code performance

16. Which debugging technique involves inserting print statements to track program execution?

Profiling

Breakpoint debugging

Trace logging

Memory analysis

17. What does a NullPointerException indicate in Java?

A pointer variable was never initialized

An attempt to use an object reference that is null

Memory has been corrupted

The garbage collector failed

18. In a try-catch-finally block, when does the finally block execute?

Only if no exception occurs

Only if an exception is caught

Always, regardless of exception occurrence

Only in production environments

19. What is the main difference between debugging and testing?

Testing finds bugs; debugging fixes them

Debugging is automated; testing is manual

Testing is only for production code

Debugging requires specialized tools

20. Which of the following best describes a checked exception in Java?

Must be caught or declared in the method signature

Occurs only during compilation

Cannot be caught by any try-catch block

Automatically handled by the JVM
