Another helpful method from the fmt package is .Scan() which allows us to get user input! Let’s see an example of this in action:

fmt.Println("How are you doing?") 

var response string 
fmt.Scan(&response)

fmt.Printf("I'm %v.", response) 

We’ll go through this line by line: First, we print How are you doing? to the terminal. Then we declare a variable, response with the type string. fmt.Scan(&response) takes the first value before a space and stores it in response. In the terminal, we would see:

How are you doing?

If we type in good and press enter, we would see:

How are you doing?
good
I'm good.

However, if we tried to type in not bad:

How are you doing?
not bad
I'm not.

Only the not part is saved, since it was separated from bad by a space. If we were expecting two values, we’d need to declare two variables ahead of time:

fmt.Println("How are you doing?") 

var response1 string 
var response2 string 
fmt.Scan(&response1)
fmt.Scan(&response2)

fmt.Printf("I'm %v %v", response1, response2) 

fmt.Scan() expects addresses for arguments, hence the & before response1 and response2. We’ll cover more about addresses in a later lesson. For now, let’s get comfortable with the syntax.
