How to build golang in windows

In this article, we will introduce how to build a Golang environment on Windows systems. Golang is an open source programming language designed to be efficient, reliable and simple. This language was originally developed by Google, so it is also called Go.

Installation and Configuration

Step One: Download and Install Golang

First, we need to download the latest version of the Golang installer from the official website (https://golang .org/dl/). We choose Windows download. After the download is complete, we double-click the installer and follow the prompts to install it. Normally, Golang will be installed in the "C:\Go" directory by default.

Step 2: Set environment variables

Next, we need to set Golang’s environment variables. We find the Path in the system environment variable, edit it, and add the "C:\Go\bin" directory. This directory is where Golang's binary libraries are stored.

Step 3: Create a Golang working directory

Before we start writing the first Golang program, we need to create a working directory. We can create such a directory anywhere and it can store our Go programs. We can create a directory named "go" under C:\. Under this directory, we can create a directory called "src". Golang requires us to place the source code under the "src" directory.

Step 4: Create the first Go program

For beginners in Golang, we usually recommend that they run a Hello World program ("Hello, World!" is the programming language standard entry procedure). First, we need to find the "src" directory we created, and then create a file named "hello.go" under this directory.

We can use any editor to write this file, but it is recommended to use Visual Studio Code, which is a free code editor and provides many useful plug-ins.

package main

import "fmt"

func main() {

fmt.Println("Hello, World!")

}

In the code, we first use A "main" package. In Golang, all programs must include the "main" package and must contain a function named "main". This function is the entry point of our program. It is the first function to be executed when the program is running.

In this code, we use a package called "fmt". This package is the formatted input and output functions provided in Golang's standard library. We use "func" to define a function named "main", and use the "fmt.Println" function in this function to print out a line of text "Hello, World!". Finally, we used the "go run" command to run the program:

go run hello.go

If all goes well, we will see the output of "Hello, World!" on the command line .

Summary

In this article, we learned how to build a Golang environment on a Windows system and wrote a Hello World program. Now that we have started the journey of Golang, I hope that our programming journey will become more and more exciting!
