Code modularity refers to the ability of a software program to be divided into smaller, independent modules. These modules should be self-contained and have their own functionality, allowing the software to be developed, tested, and maintained independently of other modules.
Benefits of code modularity:
Maintainability: Modules can be easily modified or replaced without affecting other parts of the program.
Maintainability: Changes in one module are less likely to impact other parts of the program.
Reusability: Modules can be reused in other projects, reducing development time and effort.
Testability: Modules can be tested independently, making it easier to identify and fix bugs.
Scalability: Large programs can be divided into multiple modules, making them easier to manage and scale.
Examples of modularity:
Classes and objects: Classes define a blueprint for creating objects, which represent instances of that class. Objects have their own data and methods, making them self-contained.
Libraries and packages: Libraries and packages contain reusable modules that can be integrated into different projects.
Modules in a programming language: Some languages, such as Python and Java, have built-in modules that provide standard functionality.
Key principles of modularity:
Loose coupling: Modules should have minimal dependencies on each other.
Encapsulation: Each module should expose only necessary functionality to other modules.
Inheritance: Modules can inherit properties and methods from other modules.
Polymorphism: Modules can respond differently to different inputs
