Declaring and Defining Functions

A function is a reusable block of code that accomplishes a specific task. To declare a function, you can use the func keyword. Here is the syntax for defining a basic function:

go

Below is a straightforward example of a function created using the provided format:

index


              123
            
func sayHelloWorld() {
      fmt.Println("Hello World")
}

Here is a visual representation illustrating the declaration of a function:

If we incorporate the code provided above into our program, it will transform into a reusable component that we can invoke as often as needed by calling the function. To call or execute a function, use the following syntax:


python

Here is an example of a comprehensive program that employs the previously mentioned function:

index


              12345678910
            
package main
import "fmt"

func sayHelloWorld() {
      fmt.Println("Hello World")
}

func main() {
      sayHelloWorld()
}

Within the main function, we utilized sayHelloWorld() to invoke the function. You can replicate this call as many times as needed to execute it repeatedly:

index


              123456789101112
            
package main
import "fmt"

func sayHelloWorld() {
      fmt.Println("Hello World")
}

func main() {
      sayHelloWorld()
      sayHelloWorld()
      sayHelloWorld()
}

Everything was clear?
