Problem Statement

Most programming languages offer support for subroutines. When execution changes between subroutines, different sets of variables and functions ("scopes") are available to the program. Frequently these sets are defined by the placement of the variable and function declarations ("static scoping" or "lexical scoping"). These sets may also be defined by special modifiers to the variable and function declarations. Show the different scope modifiers available in your language and briefly explain how they change the scope of their variable or function. If your language has no scope modifiers, note it.

Let's start with the solution:

Step by Step solution about How to resolve the algorithm Scope modifiers step by step in the PowerShell programming language

Source code in the powershell programming language

$a = "foo"                        # global scope
function test {
    $a = "bar"                    # local scope
    Write-Host Local: $a          # "bar" - local variable
    Write-Host Global: $global:a  # "foo" - global variable
}
