Final answer:
In a class definition, operations such as decisions and loops are specified in methods. (option 3 is the correct answer)
Step-by-step explanation:
In a class definition, operations such as decisions and loops are specified in methods. Methods in object-oriented programming encapsulate behavior associated with an object, defining how the object interacts with the outside world. Unlike properties or attributes, methods are responsible for performing actions and implementing algorithms within the class.
For instance, a method might contain conditional statements (decisions) or iterative structures (loops) to control the flow of execution. By organizing operations into methods, code becomes more modular, readable, and maintainable. Attributes, on the other hand, typically represent the state or characteristics of an object, while methods govern its behavior.
Methods play a crucial role in defining the behavior of a class, encompassing various operations, including decisions and loops, to enable effective object-oriented programming.
Understanding the role of methods in a class definition is essential for designing robust and organized object-oriented code, promoting code reuse and readability.
