Answer 1

11) Which of the following is not true about polymorphism?B. Increases overhead of function definition alwaysExplanation: Polymorphism does not always increase the overhead of function definition. It allows for the use of a single interface to represent different types, which can simplify programming and improve flexibility.12) The polympi-feature can be implemented using encapsulation?D. AbstractionExplanation: Polymorphism is a feature of object-oriented programming that allows objects of different classes to be treated as if they were objects of the same class. It can be implemented using abstraction, which allows for the representation of complex systems in simplified ways.13) What is reference to an object?C. It is pointer having address of an objectExplanation: A reference to an object is a pointer that holds the memory address of the object. It allows for indirect access to the object's variables and methods.14) How many objects can be referenced from the same variables?C. Many using array nameExplanation: An array name can be used to reference multiple objects in an array. Each element in the array can be accessed using the array name followed by the index.15) Invoking a method on a particular object is __ sending a message to that ofB. Same asExplanation: Invoking a method on a particular object is the same as sending a message to that object. It is a way of requesting the object to perform a specific action.16) Which definition best describes an object?A. Instance of a classExplanation: An object is an instance of a class. It is a concrete representation of a class, with its own unique set of attributes and behaviors.
