What is the method for initializing global variables in…

In Go language, the var keyword can be used to declare global variables and initialize them within the global scope. Global variables can be initialized by directly assigning values during variable declaration, or through the use of the init function.

Here are two common methods for initializing global variables:

1. Assign a value directly during variable declaration.

var globalVariable int = 10
var anotherGlobalVariable string = "Hello"

1. Initialize using the init function.

var globalVariable int
var anotherGlobalVariable string

func init() {
    globalVariable = 10
    anotherGlobalVariable = "Hello"
}

The init function is a special function that is automatically called when the program starts to perform some initialization operations. It can be used to assign values to global variables.

It should be noted that global variables in Go language can only be declared and initialized at the package level, not inside function bodies.
