Mr. Sylvain, so I am selectively picking the videos I have to watch to understand object oriented programming first. I would be glad if you could tell me as to which lecture talks about static functions, static variables, const functions, inline functions etc.


  • Copy a new version of your “Auto” homework. Remove every line that reads: using namespace std;
    • That will mean adding “std::” to every element in the standard namespace.
  • Create a new namespace for each object class you defined. Call it: homework_cplusplus_educator_com
  • In any block or CPP file where you may have numerous uses of “cout”, “endl”, etc., add: using std::cout;
    • or, “std::endl”, or which ever name you’d like to use without the “std::” qualifier.
  • If you put the “main” function inside the same namespace as the other classes, remove it from that namespace. (It should be in a separate file anyway.) Now you’ll need to reference your classes with their namespace, e.g., “homework_cplusplus_educator_com::Auto”.
  • Add a namespace alias, such as “homework”, so you won’t need to type the entire namespace name for “homework_cplusplus_educator_com.” (This is not just to save on your typing; the code will also be easier to read.)
  • Make sure everything still compiles and runs!
