How to install, configure and use Go language in Win system

Go language is an efficient, concise and fast programming language, which is widely used in network servers, cloud computing, distributed systems and other fields. In the Windows operating system, Golang, like other programming languages, also needs to configure the environment and settings to ensure normal compilation and operation.

This article will introduce in detail how to install, configure and use Golang in Windows systems, including downloading installation packages, adding environment variables, writing simple programs, etc.

1. Install Golang

1. Download the Golang installation package

Download from the Golang official website (https://golang.org/dl/) for Golang installation package for Windows platform, just select the latest version. Once the download is complete, double-click to install.

2. Installing Golang

Follow the installation program prompts and click "Next" to complete the installation of Golang.

2. Configure Golang environment variables

Configuring Golang environment variables is a necessary step to ensure that it can run normally in Windows systems.

1. Add environment variables

Select "Control Panel"->"System and Security"->"System", and then click "Advanced System Settings".

In the "System Properties" pop-up box, click "Environment Variables".

Add the Golang bin directory path in "User Variables"->"Path", such as: C:\go\bin.

2. Verify environment variables

Open the command line window and enter the "go version" command. If the Golang version number is displayed, the environment variable is added successfully.

3. Writing Golang programs

In Windows systems, you can use any text editor to write Golang programs. For example, Notepad, Visual Studio Code, etc.

The following uses Notepad as an example to demonstrate how to write Golang's "Hello World!" program.

1. Create and save the Go code file

In Notepad, enter the following code:

package main

import "fmt "

func main() {

fmt.Printf("Hello World!\n")

}

Note: When saving the file, the file name must end with .go, for example: helloworld.go.

2. Compile and run the program

In the command line window, use the go build command to compile the program, as follows:

go build helloworld.go

Run the program:

.\helloworld.exe

If everything goes well, the output of "Hello World!" will be displayed.

In addition, in Windows systems, you can also use the go run command to run the program directly. For example:

go run helloworld.go

Summary:

Through the introduction of this article, I believe that readers have learned how to install, configure and use Golang in Windows systems. Of course, when learning this new programming language, you still need to keep trying, learning, and practicing to master it well and take advantage of it.
