+ years since C++ was first conceived, and it has evolved to address challenges. However, many developers still use outdated techniques. To build performant, type-safe, and flexible C++ software, key concepts like resource management, modularity, and generic programming are crucial. Ways to ensure code is contemporary include guidelines and profiles. Contrary to past practices, modern C++ involves simplicity, better type-safety, and efficiency, illustrated by examples like handling resources and errors. Notably, the language has evolved with features like modules, lambda expressions, and concurrency support. The aim remains to express ideas directly, ensure resource safety, and maintain code comprehensibility and stability.
