Golang : Populate or initialize struct with values example



Tags : golang struct init populate-struct

A quick and short example on how to populate or initialize a struct with values. Pretty straight forward, but it could be confusing for those new to Golang or programming in general.

Here you go!

 package main

 import (
  "fmt"
 )

 func main() {
  myFirstStruct := struct {
 Name string
 Age  int
  }{
 Name: "Caleb",
 Age:  102,
  } // populate with value

  mySecondStruct := struct {
 Name string
 Age  int
  }{} 

 // empty or un-initialize. Golang will populate them automatically with default value
 // such as empty string or zero

  fmt.Printf("myFirstStruct struct : %+v\n", myFirstStruct)
  fmt.Printf("mySecondStruct struct : %+v\n", mySecondStruct)

 }

Output :

myFirstStruct struct : {Name:Caleb Age:102}

mySecondStruct struct : {Name: Age:0}
