I have been a software developer since 1994, mainly in telecomms and finance, both in the UK and abroad. I now work as an instructor and have taught software development classes in a range of environments.
I have so far published three courses on Udemy.
"Learn Modern C++" and "Learn Advanced Modern C++" comprehensively cover C++11 and 14 and some C++17.
"Learn Modern C++ Multithreading" teaches the principles of multithreaded programming using C++11, 14 and 17.
"Update to Modern C++" comprehensively covers all the changes from older versions to C++11/14. It is meant for more experienced programmers.
