Data Hiding
nThe private section
äincludes the data and operations that are not visible to any other class or client
äthis means that the information in the private section is “opaque” and therefore is inaccessible outside the scope of this class
äthe client has no direct access to the data and must use the public member functions
äthis is where you should place all data to ensure the memory’s integrity
