Hello Go

Write a program that prints the message "hello world" to the console.

  • The program should use the fmt package to print the message.
  • The program should be written in Golang.
## To run the program, put the code in `hello-world.go` and
## use `go run`.
$ go run hello-world.go
hello world

## Sometimes we'll want to build our programs into
## binaries. We can do this using `go build`.
$ go build hello-world.go
$ ls
hello-world hello-world.go

## We can then execute the built binary directly.
$ ./hello-world
hello world

## Now that we can run and build basic Go programs, let's
## learn more about the language.

There is the full code below:

// Our first program will print the classic "hello world"
// message. Here's the full source code.
package main

import "fmt"

func main() {
    fmt.Println("hello world")
}
