can't wait for your course, your videos are the best, after months of struggling to understand programming, i now understand everything with your videos, and i even won a coding competition thanks to you

hilgicamala

I love how you explain c++❤ very clearly

Thanks for this video! Copy constructors was one of those things that was confusing for me. It's difficult to test for deallocated memory so I could never be sure whether or not I copied correctly without having memory leak.

Very good video. I always enjoy watching your videos and being reminded of concepts that I haven't used in c++ that I haven't used in a long time since at work I've only been working on VB projects.

I gave up programming in c++ years ago ... You gave me hope to rethink my decision ....

Thanks for your video. Absolutely want to hear more about assignment operator or the Big Three. Appreciate that if you can also talk about deep copy vs shallow copy.
