golang hello world

To write a "Hello, World!" program in Go (also known as golang), you can follow these steps:

Step 1: Install Go - Download the Go compiler from the official website (https://golang.org/dl/). - Run the installer and follow the installation instructions for your operating system.

Step 2: Set up the Go workspace - Create a directory on your computer where you'll store your Go code. This directory is called the "workspace." - Set the GOPATH environment variable to the path of your workspace directory.

Step 3: Create a new Go file - Open a text editor or an Integrated Development Environment (IDE) of your choice. - Create a new file with the extension ".go" (e.g., hello.go).

Step 4: Write the Go code - Inside the hello.go file, write the following code:

package main

import "fmt"

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

Step 5: Save the file - Save the hello.go file in your Go workspace directory.

Step 6: Compile and run the program - Open a terminal or command prompt. - Navigate to the directory where your hello.go file is located. - Run the following command to compile the Go code:

go build hello.go

• This will create an executable file named hello in the same directory.

Step 7: Execute the program - Run the following command to execute the program:

./hello

• You should see the output "Hello, World!" printed in the terminal.

Congratulations! You have successfully written and executed a "Hello, World!" program in Go. This program simply prints the text "Hello, World!" to the console. It is a basic starting point for learning and testing Go code.
