package main

import "fmt"

func main() {

fmt.Println("Hello, world!")

}

Save the above program as a "hello.go" file (.go is the source code file suffix of golang). Then you can use the following command to compile and run the program:

go build hello.go
./hello

If everything goes well, you will see the output "Hello, world!".
