This is debatable, but in source files (not headers!) I like doing using namespace std, especially if it's going to be used a lot like in your source file. The static is extraneous but not harmful, it's up to you whether to keep it or not. Here the seeding instructions are only ever called once, and the std::random_device is not kept track of as it's unnecessary. Thread_local static engine = _helper_randomEngine()

private Constructor root / + Used by Excecutable for annotation sharing.

* Could even replace _helper_randomEngine by an anonymous lambda,Īvoiding the external declaration of _helper_randomEngine() */ This branching structure // is currently only two levels deep (i.e., one root Constructor // and potentially many Constructor objects pointing to it.) + // + // If this branching structure would ever contain cycles, deadlocks can + // occur in annotation code. One way to do things thread local'd (although it's really not needed here, it could all be just static) would be: std::mt19937 _helper_randomEngine() And the thread_local variables are used like any other variables which makes one forget that they are static. The other three instructions are always executed, even when they are not needed. But in this code: std::mt19937 &randomEngine() As you pointed out in your comment, they're implicitly static. Thread_local is for variables that can be accessed from multiple threads or have indefinite lifetimes. While (!words.empty() & askYN('Do you want to play again? : ')) Std::cout << 'You have ' << Max - wrong << ' more tries left ' Std::cout << ' There are ' << word.length() << ' letters left ' Std::cout << ' You Lose!

The game starts by shuffling words, then for every turn, it selects one word that the user has to figure out. The game has an edit mode for first run in which the user has to supply 6 unique words.
