function Undefined in go

Can any one help me why is the below code giving undefined:register error
I am trying to understand the call by reference and call by value.

package main

import (
"fmt"
)

type MyStruct struct {
name string
id int64
}

var (
s MyStruct
u int
)

func (u MyStruct) register() {
fmt.Println(u.name, u.id)
fmt.Println(u.name, u.id)
fmt.Println(u)
s.name = "vij"
fmt.Println(u)

}

func main() {

s := MyStruct{"deb", 11273090}
r := register()
fmt.Print("Inside Main****")
fmt.Print(s)

}

./prog.go:29:7: undefined: register

You can use markdown syntax to present the code better

Example

package main

import (
"fmt"
)

type MyStruct struct {
name string
id int64
}

var (
s MyStruct
u int
)

func (u MyStruct) register() {
fmt.Println(u.name, u.id)
fmt.Println(u.name, u.id)
fmt.Println(u)
s.name = "vij"
fmt.Println(u)

}

func main() {

s := MyStruct{"deb", 11273090}
r := register()
fmt.Print("Inside Main****")
fmt.Print(s)

}

Hi Santhosh, thanks for the suggestion. The thing is that when i format the code written in [I'm an inline link]play.golang.org/ it automatically indents the body.

Register is a method.
You need to call it by s.register()
And register doesn’t return anything.

Can you improve the title of your question please. If not done in 24 hours, the help tag will be removed.

Sorry if that was harsh ...Is this better Si

Thanks for revising it, but not much better I'm afraid. The title should be a summary of the issue, for example, for this question, it could be "function undefined in Go".

It just gives people more context into the issue without having to click on the question 😊

Edit: also no need to apologise, phrasing questions is hard. It's something you'll learn with experience.
