Back to Basics: Debugging in C++ - Mike Shah - CppCon 2022
Learn the essential principles and techniques for effective debugging in C++, including test-driven development, domain knowledge, and tools like GDB, from experienced developer Mike Shah at CppCon 2022.
- Key principles in debugging: focusing on the process of removing an observed fault in software.
- GDB is a powerful tool for debugging, especially when used in interactive mode.
-
Use of flags, such as
-gto generate debugging information, is crucial for effective debugging. - Test-driven development is essential for ensuring software correctness.
- Writing good code, reducing complexity, and using domain knowledge can make debugging easier.
- Using print debugging strategies, such as scanning and looking, is effective for understanding code.
- The importance of testing and debugging goes beyond just removing bugs, as it also helps improve code quality and maintainability.
- Debugging is not just about finding and fixing bugs, but also about improving code quality and maintainability.
- Experienced developers may still make mistakes due to various reasons, including time pressure, lack of focus, and domain knowledge.
- It’s essential to use good debugging practices, such as stepping through code, setting breakpoints, and analyzing code complexity.
- The importance of domain knowledge in debugging cannot be overstated.
- Test-driven development (TDD) is an effective way to ensure code quality and catch bugs early on.
- Debugging is an essential skill for developers, and practice with GDB and other tools can help improve debugging skills.
- Experienced developers may still face difficulties in debugging due to various reasons, including complexity, sizes of projects, and unfamiliar code.
- It’s essential to have a good understanding of the language, libraries, and frameworks used in software development.
- Debugging is not just about finding and fixing bugs, but also about improving code quality and maintainability.
