I did an extensive search and comparison among all available on line courses that focus on deep C++ programming learning combined with high level, real world application of the concepts being thought, and I noticed that the course with the highest recommendations and best comments overall was QuantNet's "C++ Programming for Financial Engineering". After finishing the course, I found it to be thorough and with very good pace, covering the basics first, including the roots of the language in "C", and then taking us through different levels where new concepts, language features and applications were explained in an easy to understand manner, up to the final level were we are faced with the task to put together all the concepts and skills learned in a set of well-thought exercises and clever quizzes. Overall, a well designed and polished course that shows the remarkable experience that Dr. Daniel Duffy and his great team of collaborators have gathered over the years, making this course the de facto gold standard for learning C++ in general and for finance engineering in particular.
