20. struct vs. class

• Default access control is:

  • public for structs;

  • private for classes.

• Common practice is to:

  • Tag access control by public and private labels in classes.

  • Use structs as if we were programming in C:

    • Forget private: everything is public by default

    • No functions allowed.

  • If you your struct needs a function, it should probably become a class.
