Step 4: Create a simple Go program

Next, let’s write a simple Hello World program to verify the compilation and running process of the Go language. Create a new folder in any location, for example named "hello", and then create a Go source code file named "main.go" under the folder with the following content:

package main

import "fmt"

func main() {
    fmt.Println("Hello, Go!")
}

Save the file After that, open the command prompt, enter the folder directory, and enter the command "go run main.go". If it is successfully compiled and run, "Hello, Go!" should be displayed on the screen.

At this point, you have successfully installed the Go language on your Win7 computer and written and run a simple Go program. I hope this article will be helpful to you and help you get started in the world of Go language smoothly.
