Here is the go code
package main
func main() {
var ax [2]int
ax[0] = 22
ax[1] = 99
bx := ax
cx := &ax
fmt.Println(ax)
fmt.Println(bx)
fmt.Println(cx)
fmt.Printf("%p
", cx)
}
When I execute it, it gives me the following output
PS C:\personal\gospace> ./bin/test
[22 99]
[22 99]
&[22 99]
0xc0420381d0
cx := &ax rightly interpreted cx as pointer. But when I print cx it prints &[22 99] and when I print &ax[0] or %p formatter for cx it rightly prints the address. Why is this behavior?
Default printing verb fmt.Println uses is %v. While printing it differentiates value vs pointer value, that's why you see & in front of cx.
fmt.Println(cx)
Next, you specifically tell fmt.Printf to use the verb %p, refer to printing section and it prints base 16 notation, with leading 0x.
fmt.Printf("%p
", cx)
