Lectures and homeworks

Build status Visitors

This is a list of lectures from the C++ for yourself course.

How to follow this course

The course is designed to be consumed from top to bottom, so start at the beginning and you will always have enough knowledge for the next video.

That being said, I aim to leave links in the videos so that one could watch them out of order without much hassle.

Enjoy! 😎
