Join Peggy Fisher for an in-depth discussion in this video Encapsulation, part of Up and Running with C++.
…Encapsulation is one of the benefits…of using object oriented programming languages.…It allows the programmer to hide the definition…of instance data and functions from the user.…This ensures that data structures and operators are used as intended.…Within a class, instance data and functions can be declared…as either private, public or protected, to explicitly enforce encapsulation.…A private member is accessible only to the…functions that are members of the same class.…
A public function of the class is accessible to the calling program.…A protected member is accessible to members…of classes that inherit from the class.…We will talk briefly about inheritance in this course.…Here is a UML diagram of a checking account.…Notice the data members are all marked as private.…This forces the calling program to access the balance…and other data using a function defined in the class.…Below the data members are the functions for this class,…and you can see they are all declared as public.…We have two constructors, three accessor methods and three mutator methods.…
