The correct response is: Private functions are only accessible to functions within the parent object, while public functions can be accessed by other objects.
Explanation:
-
Private Functions: These functions are restricted in scope and can only be accessed or called within the same class or module where they are defined. This encapsulation helps maintain control over the data and behavior of an object, protecting it from outside interference or misuse.
-
Public Functions: These functions are accessible from outside the class or module. They can be invoked by any other code that has visibility to the object, making them useful for defining interfaces and allowing interaction with the object by other parts of the program or even other programs.
