Unable to execute the program. Its showing this message: src/clock/clock_test.go:21: undefined: Noon

package clock

import "fmt"

type Clock struct { Hours int Minutes int }

// DEFINE A "Noon" FUNCTION HERE

func (c *Clock) Noon() { c.Hours = 12 c.Minutes = 0 }

func main() { clock := Clock{} clock.Noon() fmt.Println(clock) }

When i'm trying to execute above code , its printing this message: "src/clock/clock_test.go:21: undefined: Noon". Not sure what's causing this issue. Can anyone help me out with this one ?

The instructions say, "Write a Noon function that returns a new Clock ..."

You might want to review the syntax for declaring what a function returns. And you'll need to create a new "Clock" before you can set values in it, and then remember to return it.

Also, creating a "main" function isn't mentioned in the instructions, and is not part of this challenge.
