Starting with your first Go program is an exciting step into the world of Go programming. The basic structure of a Go program includes declaring a main package, importing necessary packages, and defining a main function. Let’s start with a simple “Hello, World!” program. Create a new file and name it ‘main.go’. Inside the file, write the following Go code:

package main

import "fmt"

func main() {

 fmt.Println("Hello, World!")

}

In this example, the 'fmt' package is used for formatting text output, allowing you to print messages to the console. To run the program, open your terminal and navigate to the directory containing your 'main.go' file. Type 'go run .' to execute the program, and you should see "Hello, World!" printed on your screen. This simple exercise demonstrates the ease of writing and running Go programs, setting the stage for more complex coding projects.

Diving deeper into Go programming, you’ll encounter various commands and tools that enhance your coding experience. The 'go build' command compiles your code, while 'go test' allows you to run unit tests to ensure your programs work correctly.

Go’s documentation provides numerous annotated example programs and exercises to help you learn and master the language. By experimenting with these examples and exploring Go’s rich feature set, you’ll quickly become proficient in writing efficient and robust Go code.
