I have extensive experience with C++ memory management, including manual memory allocation and deallocation using new and delete operators. I am proficient in using smart pointers like std::unique_ptr, std::shared_ptr, and std::weak_ptr to manage memory safely and avoid memory leaks. Additionally, I have worked with custom allocators and understand the importance of RAII (Resource Acquisition Is Initialization) in ensuring proper resource management.

I utilize a combination of debugging tools such as GDB and Visual Studio's debugger to identify and fix issues in C++ code. For testing, I employ unit testing frameworks like Google Test and Catch2 to write comprehensive test cases that cover various scenarios, including edge cases. I also follow a test-driven development (TDD) approach, writing tests before implementing the code to ensure robustness and reliability.

C++ is an extension of C, adding object-oriented programming (OOP) features such as classes, inheritance, and polymorphism. C++ also includes features like templates, exceptions, and the Standard Template Library (STL), which are not present in C. While C is a procedural language, C++ supports both procedural and OOP paradigms. Additionally, C++ has stricter type-checking and more advanced memory management options compared to C.

I optimize C++ code by focusing on algorithmic efficiency, reducing unnecessary computations, and minimizing memory usage. I use profiling tools to identify performance bottlenecks and apply techniques such as loop unrolling, inlining functions, and optimizing data structures. I also leverage the C++ Standard Library efficiently, avoiding unnecessary dynamic memory allocations, and using move semantics and constexpr where applicable.

I have hands-on experience with multi-threading in C++, using the C++11 threading library and higher-level abstractions like std::async and std::future. I am familiar with concepts such as mutexes, condition variables, and atomic operations to ensure thread safety. I have implemented concurrent data structures and parallel algorithms, ensuring proper synchronization and avoiding race conditions.
