Here is a code snippet :
https://play.golang.org/p/bQ5vWTlKZmV
package main
import (
"fmt"
)
type user struct {
userID int
name string
email string
}
func main() {
var users []*user
addUsers(users)
}
func addUsers(users []*user) {
users = append(users, &user{userID: 1, name: "cooluser1", email: "cool.user1@gmail.com"})
users = append(users, &user{userID: 2, name: "cooluser2", email: "cool.user2@gmail.com"})
printUsers(users)
printEachUser(users)
}
func printUsers(users []*user) {
fmt.Printf("users at slice %v \n", users)
}
func printEachUser(users []*user) {
for index, u := range users {
fmt.Printf("user at user[%d] is : %v \n", index, *u)
}
}
At above code, if I am printing the slice directly by fmt.printf
, I get only the address of the values instead of actual value itself.
output : users at slice [0x442260 0x442280]
To read to the values always, i have to callfunc
like printEachUser
to iterate the slice and get the appropriate value .
output:
user at user[0] is : {1 cooluser1 cool.user1@gmail.com}
user at user[1] is : {2 cooluser2 cool.user2@gmail.com}
Is there any way, we can read the values inside the slice of pointers using fmt.printf
and get value directly like below ? :
users at slice [&{1 cooluser1 cool.user1@gmail.com} , &{2 cooluser2 cool.user2@gmail.com}]
