How much time it will take to learn c++ if I study 2 to 3 hrs a day?

Answer 1

C++ course in SoloLearn? I read somewhere someone said the courses can be completed up in roughly 15 ~ 30 minutes, but I guess that depends.

C++ as a language itself is HUGE. I don't have any idea how one can actually say they have throroughly learned it.

The C++ standard also brings updates to the language like every 3 years or so. Then how one can say, when the language itself evolves eternally?

I think even the C++ masters are on a constant learning path, which helps them stay up to date. If one stops updating, I suppose their knowledge might become outdated sooner or later, which is not good for their career (I think).

Answer 2

it depends
a basic level of C++ can take 1-3 years maybe. It depends on the dedication and perseverance.
Master it can take more than a decade. It is a deep language with a lot of side stuff.

It should not discourage you; all that has true value has a cost.
Things that worth it take time.
