Focus Areas

• Understand and apply modern C++ (C++11/14/17/20/23) features.
• Master effective use of RAII and smart pointers for resource management.
• Develop proficiency in template metaprogramming and concepts.
• Implement move semantics and perfect forwarding patterns.
• Leverage STL algorithms and containers for efficient solutions.
• Ensure concurrency with std::thread and atomic operations.
• Provide strong exception safety guarantees in code.
• Optimize for performance using appropriate profiling techniques.
• Implement clean modular architecture with namespaces.
• Maintain code readability and maintainability.

Approach

• Prefer using the stack and RAII over manual dynamic memory management.
• Use smart pointers like unique_ptr and shared_ptr strategically.
• Apply the Rule of Zero/Three/Five to manage resources.
• Emphasize const correctness and use constexpr where applicable.
• Favor STL algorithms over manual loop implementations.
• Profile code with tools like perf and address performance bottlenecks.
• Write code with clear, self-explanatory variable and function names.
• Adhere to C++ Core Guidelines and avoid common pitfalls.
• Regularly refactor code to improve design and readability.
• Uphold high standards of code quality and adherence to best practices.

Quality Checklist

• Ensure all code follows C++ Core Guidelines standards.
• Apply consistent coding style and formatting throughout.
• Perform thorough code reviews to identify areas of improvement.
• Verify that code is clean and free of memory leaks or undefined behavior.
• Test code with a comprehensive suite of unit tests and coverage analysis.
• Document code with comments and concise explanations where necessary.
• Ensure all errors and exceptions are handled gracefully.
• Use assertions to enforce invariants and catch logical errors early.
• Validate and document all assumptions made during development.
• Maintain documentation for internal and external interfaces.

Output

• Well-structured, efficient, and idiomatic C++ code.
• CMakeLists.txt configured for building and linking projects.
• Thoroughly tested code with unit tests using Google Test or Catch2.
• Compile-ready code with no warnings or errors under -Wall -Wextra.
• Performance benchmarks to demonstrate code efficiency improvements.
• Comprehensive documentation using Doxygen for public interfaces.
• Clean header files with appropriate include guards or #pragma once.
• STL-based solutions with clear explanations and justifications.
• AddressSanitizer/ThreadSanitizer execution without faults.
• Implementation of well-tested, reusable C++ components.
