    Essential Interview Questions for C++ Developer

    How do you handle memory management in C++?

    In C++, I use RAII principles and smart pointers like `std::unique_ptr` and `std::shared_ptr` to manage memory automatically, preventing memory leaks. I am also familiar with manual memory management using `new` and `delete` when necessary, ensuring that every allocation is properly deallocated to avoid issues in the application.

    Explain the difference between virtual functions and pure virtual functions in C++.

    Virtual functions in C++ provide a base class implementation that derived classes can override. Pure virtual functions, on the other hand, have no implementation in the base class and must be implemented by any concrete derived class. A class with one or more pure virtual functions is an abstract class.

    What are some advantages of using C++ over other programming languages in the context of high performance computing in Switzerland?

    C++ offers low level control over hardware resources, which is critical for high performance computing. Its efficient memory management, combined with support for parallel processing through libraries like OpenMP, makes it well suited for demanding computational tasks common in Swiss research and development sectors. The availability of highly optimized compilers further enhances performance.

    How do you ensure code quality and maintainability in your C++ projects?

    I prioritize writing clean, modular code with clear separation of concerns. I use coding standards and guidelines, conduct regular code reviews, and write unit tests to verify functionality. I also use static analysis tools to detect potential bugs and vulnerabilities. Furthermore, I document the code thoroughly to facilitate understanding and future maintenance.

    Describe your experience with C++ standard library containers and algorithms.

    I have extensive experience using C++ standard library containers such as `std::vector`, `std::list`, `std::map`, and `std::unordered_map`, choosing the appropriate container based on performance requirements. I am also proficient in using standard algorithms like `std::sort`, `std::find`, and `std::transform` to manipulate data efficiently and effectively.

    How familiar are you with different C++ standards (e.g., C++11, C++14, C++17, C++20), and which features do you find most useful?

    I am familiar with several C++ standards, including C++11, C++14, C++17, and have some exposure to C++20. I find features like lambda expressions, smart pointers, move semantics, and constexpr functions particularly useful as they allow for writing more expressive, safer, and more efficient code. I actively try to incorporate these features into my projects.
