Procedural programming - correct answers ✔✔Programs are written as a series of step-by-step

them consists of a series of calls to procedures or functions.
Object-oriented programming - correct answers ✔✔A program is composed of a number of
interacting objects, each of which is responsible for its own data and the operations on the
data.
Class - correct answers ✔✔A blueprint or template for an object - it defines the attributes and
behaviours (methods) of objects in that class.
Information hiding - correct answers ✔✔Other classes cannot directly access the private
attributes of a class.
Constructor - correct answers ✔✔Used to create objects of a class.
Instantiation - correct answers ✔✔The creation of a new object (an instance of a class).
Encapsulation - correct answers ✔✔Data and methods are wrapped up into a single entity so

programmers can work on different classes independently and can use other classes without
needing to know how they work.
