PowerShell’s ++ and -- Operators (Redux)

A couple of days ago, I posted an article on PowerShell’s ++ and – operators. I grew up using programming languages that never implemented the auto increment/decrement operators, this was a neat new feature for me.

But I have had a couple of comments pointing out that these operators are not new, are in C# and what I describe is indeed by design. Of course they are right. The point I was making was aimed at those new to PowerShell and who probably do not have a background in programming.

For the avoidance in doubt, I know how these operators work and am well aware of them and their behavior. Smile But I do see many IT Pros that discover these operators for the first time in a PowerShell class – and it was a question I’d been asked that I posted about.  For those new to programming and to PowerShell, these two operators are a neat find and I advocate using them. But like many of PowerShell’s richer features, you have to know how they work.
