Hello World

The first program when learning a programming language is usually "Hello World". This ensures your compiler and environment are running correctly.

Structure of a Go Program

1. package main: Indicates that this file should be compiled into an *executable* (a program that can be run), not a library.

2. import "fmt": Includes the built-in fmt (format) package for input/output, such as printing text.

3. func main(): The entry point for program execution. The code inside the curly braces {} will be executed first.

MAIN.GO

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