Go language: Structure pointers

You can store the address of a structure using structure pointer.

Example

emp1 := employee{"Krishna", 1}

var empPtr *employee

empPtr = &emp1

How to access the variables of a structure using pointer?

Use '.' operator to acceess the variables of a structure.

Example

empPtr.name = "Ram"

empPtr.id = 12345

App.java

package main

import "fmt"

func main() {
 emp1 := employee{"Krishna", 1}

 fmt.Println("name : ", emp1.name)
 fmt.Println("id : ", emp1.id)

 var empPtr *employee
 empPtr = &emp1

 empPtr.name = "Ram"
 empPtr.id = 12345

 fmt.Println("\nname : ", emp1.name)
 fmt.Println("id : ", emp1.id)
}

type employee struct {
 name string
 id   int
}

Output

name :  Krishna

id :  1

name :  Ram

id :  12345
