Your First Line of Go

Here's your first Go program:

example.go
package main

import "fmt"

func main() {
    fmt.Println("Welcome to Go!")
}

package main declares this as a runnable program. import "fmt" loads Go's printing package so you can output text.

Every Go program starts in func main(). Everything between the curly braces runs when you hit play.

fmt.Println() prints text to the screen, followed by a new line (note the capital P, Go is case-sensitive).

Exercise: Make It Speak

Add one line inside main() to make the program print:

example.go
Hello Go

That's it. One line.
