Distinguish between void functions and non-void functions with the help of an example.

Void functions are those functions that do not return any value. They may or may not contain a return statement, but even if the return statement is present, it returns no value. When such a function is called, it automatically returns None. Void functions are also called non-fruitful functions.

Example of a void function:

def msg():
    print("Welcome")
msg()

In this example, the function msg() only prints a message and does not return any value. Hence, it is a void (non-fruitful) function.

A non-void function is a function that returns a value using the return statement after execution. The value returned is passed back to the calling statement. Non-void functions are also known as fruitful functions.

Example of a non-void function:

def add(a, b):
    return a + b
result = add(4, 6)
print(result)

In this example, the function add() returns the sum of two numbers using the return statement. Hence, it is a non-void (fruitful) function.
