Creating and Executing Simple Programs in Go

Creating and executing simple programs in Go is straightforward and requires only a few steps. Here is a brief guide to help you get started.

The following steps are necessary.

1. Install Go. First, you need to install Go on your computer. You can download the latest version of Go from the official website (https://golang.org/dl/). Follow the instructions for your specific operating system to install Go.
2. Set up your Go environment. Once Go is installed, you need to set up your Go environment. This includes setting the GOPATH environment variable, which is the directory where Go stores your code and its dependencies.
3. Create a new Go file. Open a text editor and create a new file with the extension “.go”. For example, you could create a file called “hello.go”.
4. Write your Go code. In your new file, write your Go code. For example, you could write a simple “Hello, World!” program like this.

package main

import "fmt"

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

5. Save your file. Save your file in the directory specified by your GOPATH environment variable.
6. Compile your code. Open a terminal or command prompt and navigate to the directory where your Go file is located. Then, run the following command to compile your code.

go build hello.go

This will create an executable file called “hello” in the same directory.

7. Execute your program. Finally, run your program by executing the “hello” executable file:

./hello

You should see the output “Hello, World!” printed in your terminal.

Congratulations, you have just created and executed a simple program in Go! From here, you can continue to explore the language and its features to build more complex and powerful applications.
