When we are writing any program, apart from making sure that it serves the required purpose, we must make sure that we also take the following aspects into consideration:
- Code reuse: We must try to implement the program flow in such a way that common functionalities can be used across multiple modules.
- Code maintenance: We must accept that any program code that's written is bound to have a few bugs. However, we must ensure that the code that's written is clear and structured enough that it's understandable and easy to maintain.
- Design patterns: Design patterns allow us to write programs in such a manner that there is a common template/structure/functionality that can be used across multiple modules. This ensures that the performance of the application is not compromised, which is a key aspect of any program application...
