What is the importance of return statements in programming?

Return statements are crucial as they allow functions to output values, enabling further use of those results.

Can you give me an example of a return statement in Python?

Sure! In Python, a simple example is:

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

This function returns the sum of a and b.

What happens if I forget to use a return statement?

If you omit a return statement, the function will return None by default, which may lead to unexpected behavior.

Are there any programming languages that don't use return statements?

Yes, some languages like JavaScript allow functions to return values implicitly, but using explicit return statements is still a good practice.
