Which command is used to create an array?

• A. array MyArray = (1, 2, 3)
• B. MyArray[] = 1, 2, 3
• C. $MyArray = @(1, 2, 3)
• D. $MyArray = [1, 2, 3]

Answer: (C)

The command that correctly creates an array is represented by the notation $MyArray = @(1, 2, 3). This syntax is specific to PowerShell, which uses the @() construct to define an array. When you use @(), you are explicitly indicating that you are creating an array object, even if the array contains only one item.

In contrast, the other commands do not follow the proper syntax for array creation in PowerShell. The first option suggests using a syntax that is not compatible with PowerShell language rules, while the second uses an incorrect format for array assignment. The fourth option, while it may appear to create a collection, does not explicitly define the structure as an array within PowerShell.

Understanding the differences in syntax is crucial for proper array handling in programming, especially in PowerShell, which relies heavily on these constructs for array and collection manipulation.
