Golang : Valued expressions and functions example

Writing this simple example down here as a reminder for myself on how to use valued expressions in Golang. Nothing complicated, just a simple reminder for my old brain.

Here you go!

 package main

 import (
  "fmt"
 )

 func main() {

  // functions
  g := func(x int) int { return x * 9 }
  f := func() int { return 9 }
  fmt.Println(g(f()))

  // arithmetic
  fmt.Println("One plus five is ", 1+5)

  value := 2
  fmt.Println(value * 2) // 4
  fmt.Println(float64(value*16) / 2)

 }

Output :

81

One plus five is 6

4

16
