The following tutorial column will introduce to you the difference between go’s & and *, as well as application scenarios. I hope it will be helpful to friends in need! & In go, the address character is taken directly , but the second item returns &{} instead of 0x...Address

I don’t quite understand this

package mainimport "fmt"type Test struct {
    name string}func main() {
    test := Test{"test"}
    fmt.Println(test)
    //结果{test}

    testa := &Test{"test"}
    fmt.Println(testa)
    //结果 &{test}

    testc := &Test{"test"}
    fmt.Println(*testc)
    //结果 {test}


    testd := &Test{"test"}
    fmt.Println(&testd)
    //结果 0xc000006030}
