Step-by-Step Solution
Solution:
Step 1: Understand the range check
We want to check if $value is between 10 and 20 inclusive, so it should be greater than or equal to 10 and less than or equal to 20.Step 2: Identify correct operators
Use '-ge' for greater than or equal and '-le' for less than or equal. Combine with '-and' to ensure both conditions are true.Final Answer:
($value -ge 10) -and ($value -le 20) -> Option BQuick Check:
Both comparisons use inclusive operators and are combined with '-and' [OK]
Quick Trick: Use '-ge' and '-le' with '-and' for inclusive range checks [OK]
Common Mistakes:
- Using '-gt' and '-lt' excludes boundary values
- Using '-or' instead of '-and' allows values outside the range
- Mixing assignment '=' instead of comparison operators
