Final answer:
To re-use most of the code for a similar app that isn't related to parking, you can abstract common functionalities into separate functions or classes. Only the specific details related to the new app need to be modified. This approach allows for scalability and flexibility.
Step-by-step explanation:
In order to re-use most of the code for a similar app that isn't related to parking, you can identify the common functionalities that can be abstracted into separate functions or classes. For example, if your parking app involved displaying information about parking spots in different cities, you can create a separate function or class to handle the retrieval and display of city-specific information. Then, in your new app, you can modify the variables like 'city' and 'rates' to represent different information relevant to the new app, such as different locations or categories of information.
This way, the core code can be reused, while only the specific details related to the new app need to be modified. This approach allows for scalability and flexibility, as it separates the common functionalities from the specific implementations.
One example of this reusability is in an app about restaurant recommendations. The core code for retrieving and displaying information about restaurants, such as their names, ratings, and reviews, can be reused from the parking app. The variables 'city' and 'rates' can be modified to represent different cities and types of restaurants. This way, the code for handling the display and retrieval of information remains the same, but the specific details related to restaurants are adjusted to fit the new app.
