A: A class is a programming concept that defines a blueprint or template for creating objects that have certain properties (data) and behaviors (methods). It is not a data type, structure, or format, but rather a higher-level construct used in object-oriented programming (OOP) to create objects with specific characteristics and functionality. A class can be thought of as a user-defined data type that encapsulates data and methods into a single entity. When you create an instance of a class, you are creating an object that has its own set of properties and behaviors, as defined by the class.
