Add default values to function arguments.

In programming languages such as Python, default values for function arguments are set directly in the function definition. This allows calling the function without specifying these arguments, and they then take the predefined values.

Example in Python:

def greet(name="Guest", greeting="Hello"):
    print(f"{greeting}, {name}!")

# Function calls

greet()  # Outputs: Hello, Guest!
greet("Anya")  # Outputs: Hello, Anya!
greet(greeting="Hi")  # Outputs: Hi, Guest!

This approach simplifies function usage and makes the code more readable and flexible.
