What are functions in programming?

Functions are reusable blocks of code that perform a specific task. They help organize and modularize code.

Can you give me an example of a function?

Sure! Here's a simple example in Python:

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

This function takes a name as input and returns a greeting.

How do I call this function?

You can call the function by using its name followed by parentheses. For example:

greet('Alice')

This will return 'Hello, Alice!'.

What if I want to pass multiple arguments?

You can define a function with multiple parameters. For example:

def add(a, b):
    return a + b

You can call it like this: add(5, 3) which will return 8.
