How do I separate interface and implementation cleanly in high-performance C++?

In high-performance C++, separating interface and implementation is crucial for maintaining clean code and achieving optimal performance. This approach not only improves code readability and maintainability but also allows for better optimization opportunities.

Example: Separating Interface and Implementation

// MyClass.h - Interface #ifndef MYCLASS_H #define MYCLASS_H class MyClass { public: MyClass(); void DoWork(); private: int data; }; #endif // MYCLASS_H // MyClass.cpp - Implementation #include "MyClass.h" #include MyClass::MyClass() : data(0) {} void MyClass::DoWork() { std::cout << "Working with data: " << data << std::endl; // Perform work here... }

This implementation splits the header and source files clearly denoting an interface in `MyClass.h` and its functionality in `MyClass.cpp`. It ensures that the header file remains clean without any implementation details interfering, which can lead to faster compilation times and cleaner dependencies.
