Answer 1

Codecademy is using the scope resolution operator to access cout from the std namespace.

SoloLearn is importing the entire std namespace into the current namespace. From what I've been reading, this is bad practice. Something about it possibly causing conflict with identifiers.

Sololearn is totally free while Codecademy asks you to get a pro version for money.
Sololearn has an app for mobile devices, which is a big advantage. -Lastly, Sololearn provides you a logbook (or something) to save your codes.

On the other hand, Codecademy is widespread and well-known among software world.

Answer 3

As a Sololearn learner, should I try Codeacademy?
