Built-in functions

Certainly. Take a look into the C++ standard library. https://www.geeksforgeeks.org/cpp-stl-tutorial/

Michelle SoloLearn doesn't cover all of STL, but we are moving slowly towards community-generated content. Assuming that you are using the SoloLearn mobile app, you can find lessons on utilizing some of the mentioned headers, as well as common sorting algorithms. <vector>, for instance: https://www.sololearn.com/learn/261/?ref=app

The website does lack features available on the mobile app (challenges, community generated lessons/assignments, news feed for user activity, code comments, etc. Added a link for ref) Sololearn is still in the process of porting some of the features. https://www.sololearn.com/Discuss/1172089/?ref=app

Thanks a bunch! I appreciate it! Are they gonna cover any of that here on sololearn?

Hatsy, I was mostly doing the lessons on the mobile app until I found I could continue it on my laptop. Are there different features on the mobile app that you don't see through a standard browser on a laptop? I just finished Functions and am starting on Classes. After going through Functions and seeing a few Size and Time (isn't Sum one too?) I just thought the concept of being able to reference a library might be handy so students don't have to reinvent the wheel.
