Hello Bar - Printf

When printing values of variables it might be better to use the Printf function than the Println as the former allows us to use placeholders such as %s and be more precise where we would want to put a space and where don't. These formatting placeholders are similar to what we have in other programming languages, but Go has a few additional placeholders. Specifically %s isn't special. It stands for strings.

package main

import (

func main() {
    name := "Bar"
    fmt.Printf("Hello %s\n", name)
