What does the following code print to the console? var sauces [3]string sauces[0] = "ketchup" sauces[1] = "bbq" sauces[2] = "mayo" fmt.Println(sauces)	`[ketchup bbq mayo]` is printed. `sauces` is declared as an array that holds three `string` elements. The string `ketchup` is added in the first position of the `sauces` array. The string `bbq` is added in the second position of the `sauces` array. The string `mayo` is added in the third position of the `sauces` array. The `sauces` array is then printed to the console with the `fmt.Println` function.
What does the following code print to the console? numbers := [3]int{20, 22, 29} fmt.Println(numbers)	`[20 22 29]` is printed to the console. This example uses Go's shorthand syntax to create an array. Go arrays have a fixed length and the `numbers` array in this example can only hold three items.
What does the following code print to the console? primes := [5]int{1, 2, 3} fmt.Println(primes)	`[1 2 3 0 0]` is printed to the console. The `primes` array is declared to contain five integer values. Only three integer values are set explicitly, so the final two elements use the "zero value" for integers. The zero value for integers is `0`.
What does the following code print to the console? cheeses := [5]string{"parm", "blue", "gouda"} fmt.Println(cheeses[2])	`gouda` is printed to the console. `cheeses[2]` fetches the third item from the `cheeses` array.
What does the following code print to the console? countries := [2]string{"peru", "argentina"} countries[1] = "uruguay" fmt.Println(countries)	`[peru uruguay]` is printed. The `countries` array is initially set to contain `peru` and `argentina`. Then the second element of the array is replaced with `uruguay`.
What does the following code print to the console? colors := [2]string{"red", "yellow", "blue"} fmt.Println(colors)	This code returns the following error: `array index 2 out of bounds [0:2]`. The `colors` array is declared to only contain two strings. Go will throw an error if you try to add a third string to an array that's declared to only contain two strings.
What does the following code print to the console? pastas := [4]string{"carbonara", "pesto"} fmt.Println(len(pastas))	`4` is printed. The `pastas` array contains two values that are set and two string "zero values". The zero value for a string is the empty string. The `len()` function returns the number of items in an array.
What does the following code print to the console? soups := [4]string{ "pho", "chicken noodle", "sancocho", } fmt.Println(soups[2])	`sancocho` is printed. `soups[2]` returns the third item in the `soups` array.
What does the following code print to the console? balkans := [2]string{ "croatia", "serbia" } fmt.Println(balkans)	The code returns the following error: `syntax error: unexpected newline, expecting comma or }`. When the multiline array syntax is used, each element must be followed by a comma. This code should be refactored as follows: balkans := [2]string{ "croatia", "serbia", } fmt.Println(balkans)
