Code:
package main
import "fmt"
func main() {
fmt.Println("hello world")
}Let's break down the code step by step:
-
Package Declaration: The first line
package maintells the computer that this code is part of a package named "main". A package is like a collection of code that serves a specific purpose. In this case, the package named "main" is a special package because it contains themainfunction, which is the entry point of the program. -
Import Statement: The line
import "fmt"is used to bring in some extra functionality from another package called "fmt". This package provides functions to format and output text. -
Function Definition: The next part
func main()defines a function namedmain. A function is like a little piece of code that does a specific task. Themainfunction is special because it's the starting point of the program's execution. Whatever is inside this function will be executed when the program runs. -
Print Statement: Inside the
mainfunction,fmt.Println("hello world")is written. This line is using thePrintlnfunction from the "fmt" package. It's asking the computer to print the words "hello world" on the screen.
So, when you put all these parts together and run the program, it will do just one thing: show the words "hello world" on your screen.
It's like telling the computer, "Hey computer, I want you to show me the words 'hello world'." And the computer follows your instructions and shows those words to you!
