Swift - Control Flow

Which of the following is the correct syntax for a switch case with a where clause in Swift?

let number = 10
switch number {
    case let x where x > 5:
        print("Greater than 5")
    default:
        print("5 or less")
}

Acase let x if x > 5:

Bcase x where x > 5:

Ccase let x where x > 5:

Dcase x if x > 5:

Step-by-Step Solution

Solution:

Step 1: Identify correct pattern binding syntax
In Swift, to bind a value in a case, use let x before the where clause.
Step 2: Check the where clause usage
The where clause follows the pattern binding, so case let x where x > 5: is correct.
Final Answer:
case let x where x > 5: -> Option C
Quick Check:
Pattern binding with let + where clause = case let x where x > 5: [OK]

Quick Trick: Use 'let' before variable, then 'where' for condition [OK]
