Thanks @ralves for clarifying.
I have taken the C++ course from Construct, but felt that the course required additional explanations on certain topics, epecially for a beginner like me. i had mentioned in a previous post all the things that could be improved in that course Clarification on the content of C++ for Robotics Basics. I think new users, especailly ones that are new to C++ will benefit if the queries mentioned in the post was answered in the course itself.
