At last, video tutorial 4 is here! I would like to apologize for the terrible delay, and thank you so much for your patience! 🙂
You may notice some mistakes in the screenshots though – in particular when the code that converts between integers and floating point numbers is displayed. The highlighted code is correct, but the way that it appears in the following slides (without the float and int conversions) is incorrect.
The transcript for this will be available shortly, and the fifth video tutorial is in the works. Thank you so much, especially to all those who have left comments of encouragement! They really keep me going :). I hope you find these helpful!
