In between those curly braces, we will type the code to be executed if the statement was to
return true. As the statement will return false, any code inside those curly braces will be
skipped, and the program will move on to whatever is next.
The else statement
What if we want to do something else when an if statement evaluates as false? For this,
we have what is called the else statement. This allows us to do something when it evalu-
ates as true; otherwise (if it does not evaluate as true), do something else.
The else statement must be accompanied by an if statement to work.
In the following screenshot, you can see how an else statement is structured:
As you can see, it is structured fairly similar to the if statement itself, the difference be-
ing it doesn't need something to check for it to function. Any code in the curly braces that
follows the else statement will be executed if the if statement returns false instead of
true. Should the if statement return true, then the code for the else statement would be
skipped.
The else if statement
What if we want to do something when the if statement returns false, but we only want
to do it if something else returns true at the same time?
For this, we have the else if statement. If you guessed it being a combination of the
if and else statements, then you are correct. The else if statement allows us to do
something when the original if statement isn't true and another if statement is true.
That may be confusing, so let's look at an actual else if statement in use.
