打印指针变量

Question

I created 2 Vertex objects below- q & q.

Now, when I print the pointer variable q = &Vertex, I expected it to be the memory address, why is it printing the - &{1,2}

Output:

{1 2} &{1 2}

Program:

package main

import "fmt"

type Vertex struct {
    X, Y int
}

var (
    p = Vertex{1, 2}  // has type Vertex
    q = &Vertex{1, 2} // has type *Vertex
)

func main() {
    fmt.Println(p, q)
}

From https://golang.org/pkg/fmt/ :

Println formats using the default formats for its operands

If you want to print in a specific way, you need to use fmt.Printf() and supply the format you want.
