What are if-else statements in programming?

What are if-else statements in programming?

If-else statements are conditional statements that execute different code blocks based on whether a condition is true or false.

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

Sure! Here's a simple example in Python:

age = 18
if age >= 18:
    print('You are an adult.')
else:
    print('You are a minor.')

What happens if I have multiple conditions?

You can use 'elif' to check multiple conditions. For example:

if age < 13:
    print('You are a child.')
elif age < 18:
    print('You are a teenager.')
else:
    print('You are an adult.')

Are if-else statements used in all programming languages?

Yes, most programming languages have some form of if-else statements, though the syntax may vary.
