- Manage optional values with
std::optional - Use
std::anyfor type safety - Store different types with
std::variant - Time events with
std::chrono - Use fold expressions for variadic tuples
- Manage allocated memory with
std::unique_ptr - Share objects with
std::shared_ptr - Use weak pointers with shared objects
- Share members of a managed object
- Compare random number engines
- Compare random number distribution generators
