What will you recommended after finishing a course in Sololearn ?

Question

i just finished the Sololearn C++ course , it really teached me a lot but there is still quite some things that it didn't show me , what course / website would you recommend me to ?

Answer 1

After I finished the C++ course here, I went on learning a lot about the Standard Template Library (STL). There are two excellent references for this:
http://www.cplusplus.com/reference/
and
https://en.cppreference.com/w/cpp

It might also be interesting to implement some of the commonly used Data Structures, it will not only help you understand them better, but also give you a lot of practice in writing C++. You could start here on Sololearn with that, for example:
https://www.sololearn.com/learn/773/?ref=app

While it is important to write code in order to practice, you should also look at other people's codes, what they are doing and how. There's a lot you can learn from others, and there are some really good C++ programmers here on Sololearn you can follow for that purpose.
