PowerShell - String Operations

You want to format a list of product prices to show as currency with 2 decimals using the -f operator inside a loop. Which code snippet correctly formats each price stored in $prices array?

Aforeach ($p in $prices) { "Price: $p:C2" }

Bforeach ($p in $prices) { "Price: {0:C2}" -f $p }

Cforeach ($p in $prices) { "Price: {1:C2}" -f $p }

Dforeach ($p in $prices) { "Price: {0:C}" -f $prices }

Step-by-Step Solution

Solution:

Step 1: Understand the currency format specifier
The format specifier 'C2' formats a number as currency with 2 decimal places.
Step 2: Check loop and placeholder usage
foreach ($p in $prices) { "Price: {0:C2}" -f $p } correctly loops over each price $p and formats it with {0:C2} and passes $p as argument. foreach ($p in $prices) { "Price: $p:C2" } incorrectly tries to format inside string without -f. foreach ($p in $prices) { "Price: {1:C2}" -f $p } uses {1:C2} but only one argument is passed, causing error. foreach ($p in $prices) { "Price: {0:C}" -f $prices } passes entire array $prices instead of single price.
Final Answer:
foreach ($p in $prices) { "Price: {0:C2}" -f $p } -> Option B
Quick Check:
Loop each price with {0:C2} and $p argument = A [OK]

Quick Trick: Use {0:C2} with single variable inside loop [OK]

Common Mistakes:

Using wrong placeholder index
Passing whole array instead of single item
Trying to format without -f operator
