Answer 1

Has anyone found a visible SoloLearn document for this topic? Otherwise folks are just accumulating personal anecdotes and speculation.

While discovery and sharing are part of the learning model, Sololearn should be providing some basic details about their platform. I've yet to locate any official FAQ which even highlights the differences between the web based sololearn.com vs the iOS apps vs the Android Apps. (If you haven't looked, the differences are substantial.)

Answer 2

For C++, memory manipulation do not work fine.
In a structure, each attributes are supposed to be stored contiguously but it seems it is not the case. I tried to use it in the code below (which work fine on CppDroid and Compiler, two C++ compiler's apps) and it made unwanted behavior in the code playground.
