Answer:
when user wants duplicate copy of the object
Explanation:
Encapsulation are one of the key foundations of object-oriented programming (OOP). It involves the bundling of data or information with the methods and various techniques which operate on that data.
It can be used in hiding the true values or state of a structured data object that is in a class, preventing unauthorized parties' direct access to them.
The circumstances that can be allowed in returning a reference to the existing Engine is when user wants duplicate copy of the object.
Answer:
myInt=40
myFloat=4.8
Explanation:
First look at the function definition .It has two arguments intVal is passed by reference while floatVal is passed by value.So the changes done on the myInt variable will be reflected on the original argument because when a variable is passed by reference the the changes are reflected on the original argument but when a variable is passed by value the function created a duplicate copy of it and work on them so changes are not reflected on the original argument.So myInt will get doubled while myFloat will remain the same.
