 The `else` clause always follows the `if` statement.

+## Frequently Asked Questions
+
+### 1. How to use if condition in PowerShell?
+
+In PowerShell, the `if` statement checks whether a condition is true before running a block of code. Here is how to implement it:
+
+```shell
+$number = 10
+if ($number -gt 5) {
+  Write-Output "Number is greater than 5"
+}
+```
+
+### 2. Does PowerShell have else if?
+
+Yes, PowerShell supports `elseif` for multiple conditions.
+
+```shell
+$score = 75
+if ($score -ge 90) {
+  Write-Output "Grade: A"
+} elseif ($score -ge 75) {
+  Write-Output "Grade: B"
+} else {
+  Write-Output "Grade: C"
+}
+```
+
+### 3. Can I use ++ in PowerShell?
+
+Yes. PowerShell supports the unary `++` and `--` operators for incrementing and decrementing values. It also supports unary `-` for negation.
