Modern C++ features
Use C++11 to C++23 features for safer code.
📖 Key ideas
- auto, range-for, nullptr, lambdas.
- Move semantics avoid expensive copies (std::move).
- Smart pointers replace manual new/delete.
- std::optional, std::variant, structured bindings: auto [a, b] = pair.
- constexpr for compile-time computation.
💡 Real-life example: Modern C++ is the same car with power steering, airbags and GPS added.

std::optionalValue that may be absent
