Final answer:
Using the object-oriented approach in creating a new system for a medium-sized supermarket allows for modular, reusable, and maintainable code. By organizing code into objects, representing real-world entities and operations become easier. Additionally, code reusability and modularity are promoted.
Step-by-step explanation:
When creating a new system for a medium-sized supermarket, using the object-oriented approach makes sense because it allows for the creation of modular, reusable, and maintainable code. The object-oriented approach focuses on organizing code into objects, which are instances of classes that have properties and methods. In the case of a supermarket system, you could have objects like 'Product' which represents a product in the store, 'Employee' which represents an employee working in the store, and 'Transaction' which represents a transaction made by a customer.
Each of these objects can have their own set of properties and methods, making it easier to represent the real-world entities and operations that occur in a supermarket. For example, the 'Product' object could have properties like 'name', 'price', and 'quantity', and methods like 'getPrice()' and 'updateQuantity()'. The 'Employee' object could have properties like 'name', 'role', and 'hourlyRate', and methods like 'calculateSalary()' and 'updateRole()'. By building the system using these objects and their interactions, it becomes easier to understand, modify, and extend the code in the future.
The object-oriented approach also promotes code reusability and modularity. For example, you can create a 'Discount' class that provides methods for calculating discounts on products, and then reuse this class in different parts of the system where discounts are needed. This saves time and effort, as you don't have to reinvent the wheel each time a discount calculation is required.
