We can also include a short variable declaration before we provide a condition in either if or switch statements. Here’s the syntax:

x := 8 y := 9 if product := x * y; product > 60 { fmt.Println(product, " is greater than 60") }

In our if statement, we first declare product. Notice that product is separated from the condition using a semi-colon ;. We can also have a short variable declaration inside a switch statement:

switch season := "summer" ; season { case "summer": fmt.Println("Go out and enjoy the sun!") }

One thing to keep in mind when using the short variable declaration in if or switch statements is that the declared variable is scoped to the statement blocks. In programming, scope refers to where variables can be accessed. Having the variable scoped to the if… else if… else statement or switch statement means that variable is only accessible within the blocks of those statements and not anywhere else.

x := 8 y := 9 if product := x * y; product > 60 { fmt.Println(product, " is greater than 60") } fmt.Println(product)

The code above will throw the error:

./main.go:11:13: undefined: product

Even though we defined product in our code snippet, we can only access product inside of the if block. Therefore, when we try to access it outside of the block, the compiler throws an error. We say that product is out-of-scope outside the if statement.

Let’s use this handy shortcut in our code.



In main.go we have an if statement and a switch statement that can each use the short declaration.

Let’s first change the if statement to declare success inside the statement. You’ll have to delete the provided success variable.


Turn your attention to the switch statement and do the same for the numOfThieves:

  • Declare numOfThieves inside the switch statement.
  • Remove the numOfThieves outside of the switch statement.
