Multi-Paradigm Programming with Modern C++ - Pimpl Idiom

The video tutorial discusses the challenges of class declarations in C, particularly the exposure of private functions and unnecessary includes in header files. It introduces the pimple pattern as a solution, which involves hiding class internals in a separate implementation class. This pattern reduces dependencies and improves compilation speed. The tutorial provides a step-by-step guide on implementing the pimple pattern, handling initialization, and maintaining const correctness. It also discusses the advantages and disadvantages of the pattern, such as reduced complexity and potential issues with heap allocation. The video concludes with a preview of the next topic: modules in C.
