Else If Expression

In the last task, you might have noticed that we didn't consider the case when we print not valid age (for example, -1 or -6). Therefore, there should be a way to modify our code to predict such things.

If you want to add one more condition to check it, use else if statement:

So our modified code for the previous task will look as follows:

The code initially checks if the age is valid. If the first statement is true the program prints a message if not - goes to the second condition. If the second condition is true and the user is over (or equal to) 21 years old the code prints a message, otherwise, both conditions are false and the customer is less than 21 and can’t buy alcohol.

You can add as many conditions using else if statement as you want.

Tutto è chiaro?
