Advanced C++ for Robotics(Part 1)
Unit 3: Classes and Objects in C++

I would like to suggest to edit the following:

Demo 3.1

  • cd ===> cd ~/catkin_ws/src/
  • mkdir unit3_demos
  • add this ==> cd unit3_demos/
  • touch demo_31.cpp

Demo 3.2

  • add this command ==> touch demo_32.cpp

Demo 3.3

  • ./demo_32 ==> ./demo_33

Demo 3.4
there is an error when compiling the code and in order to solve it. make the member of the Class IceTray public:

I’m not sure if this is the right way to suggest the edit, if not please advice :slight_smile:

Kind regards
