Maybe I’m wrong, but I think I may have found an error in the code checks on this lesson. I was at the point in the lesson where it says, "1. Given the string star , create a pointer called starAddress that holds the address of star .

I used the following code:

func main() {
star := “Polaris”
// Add your code below:
var starAddress *string
starAddress = &star
fmt.Println(“The address of star is”, starAddress)

This code did not pass the check for step one. It gives me the following error:

Did you assign starAddress the address of star ?

However, my code ran fine and even gave me my intended output:

The address of star is 0xc0000101e0

Am I not understanding this correctly? I declared my variable, starAddress, and used the asterisk to state that this would hold the address for a string variable. I then set the value of starAddress to the address of the star variable using the ampersand.

The hint states, “You may initialize starAddress first and then assign it a value or directly declare it using := .”

If I change my code to the following, it passes the first check:

func main() {
star := “Polaris”
// Add your code below:
starAddress := &star
fmt.Println(“The address of star is”, starAddress)

However, if I’m understanding it correctly, what I did differently here was directly declare it instead of declaring it first and then assigning a value. If this is the case, either the hint is incorrect that I can declare it first and then assign it a value or the code check is incorrect and not allowing me to do so.

After passing the first check, I changed my code back to what I used first, declaring my variable and then setting a value, and it passed the second check and ran fine, again giving my my intended output:

The address of star is 0xc0000101e0

If I’m wrong, please explain how so that I can better understand this. Any help would be very much appreciated.

I don’t think you are wrong. I have this issue with many of the test on this site. Sometimes the test and lesson is designed to enforce something specific. In this case I think its just the test. My code was the last code snippet you posted.
