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

go

index.go

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:

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

go

index.go

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:

go

index.go

Select the appropriate line of code to call the defined function:
