Ask HN: Project Ideas to Learn C++11 Features

1 point·koots··6 comments

Hello,

I know C++03 and I want like to learn modern C++ features(at least C++11), but I always forget them with no practice. Please recommend some mid size project ideas.

I'm not sure what a good mid-size project would look like, but one thing that really helped me was implementing structures/algorithms using C++11's features. It aided in not just getting a feel for them, but also what finding out features I liked and didn't.

An example might be implementing a linked-list or tree with `unique_ptr`, while using conventional pointers for the doubly-linked `prev` part. The goal being exploring the idea of ownership and automatic memory management.

Personally, the most helpful way I learned about using C++ was to try features and hear which ones people liked/disliked and why. The discussion (and sometimes drama!) made things more memorable.

I see your point, but I want a project I can learn from and to add to my portfolio.

Perhaps a raytracer? Those are often performance-oriented and employ C++ so the subject matter would be practical. A look into threading, memory ownership, and tricks like `constexpr` could all be utilized.

A ray tracer sounds good. Thank you.

Make a roguelike game. A basic one can be implemented in a couple of KLOC and will make good use of STL, algorithms, and memory management. Best of all when you are finished you will have a fun game to play!

The annual 7DRL challenge in which you have 7 days to make a roguelike is starting next week. See https://itch.io/jam/7drl-challenge-2019 for details.

Sounds interesting, although I will not be able to join it this time.

But it seems that a game is my only option, although I was trying to think of a non-game project, but I can't come up with another idea.
