What is modular programming and can you give me some examples?

Modular programming is a software design technique that emphasizes separating a program into distinct modules. Each module handles a specific part of the program's functionality. For example, in a web application, you might have separate modules for user authentication, data processing, and user interface.

Can you explain why modular programming is beneficial?

Certainly! Modular programming enhances code reusability, makes debugging easier, and allows for better collaboration among developers. It also simplifies maintenance since changes in one module can often be made without affecting others.

Could you provide a simple code example of modular programming?

Sure! Here's a simple example in Python:

# module1.py

def greet(name):
    return f'Hello, {name}!'

# module2.py

from module1 import greet

def main():
    print(greet('Alice'))

if __name__ == '__main__':
    main()

In this example, module1.py contains a function to greet a user, while module2.py imports that function and uses it.

What are some real-world applications of modular programming?

Real-world applications include large-scale software systems like operating systems, web applications, and game development. For instance, in a web application, different modules can handle user accounts, payment processing, and content management independently.
