C++ is often treated like an old grandpa language: powerful, cranky, and assumed to have stopped evolving sometime around the arrival of Java, C#, and Python.

Except it didn’t.

C++ changed dramatically with C++11. Since then, new versions have followed roughly every three years, bringing a steady stream of features that make the language safer, more expressive, and, occasionally, less hostile to human beings.
