What are some examples of nested if-else statements?

Can you explain what nested if-else statements are?

Sure! Nested if-else statements are if-else statements placed inside another if-else statement, allowing for more complex decision-making.

Can you give me an example of a nested if-else statement?

Of course! Here's a simple example in Python:

age = 20
if age >= 18:
    print('You are an adult.')
    if age >= 65:
        print('You are a senior citizen.')
    else:
        print('You are not a senior citizen.')
else:
    print('You are a minor.')

What happens if the conditions are not met?

If the conditions are not met, the program will execute the code in the else block, if it exists. If there are no else blocks, it simply moves on.

Are there any best practices for using nested if-else statements?

Yes! Keep them readable, avoid deep nesting, and consider using switch statements or dictionaries for better clarity when possible.
