Swift - Data Types

let a: Int = 7
let b: Int = 2
let result = ???

Alet result = Double(a / b)

Blet result = Float(a / b)

Clet result = Float(a) / Float(b)

Dlet result = a / b as Float

Step-by-Step Solution

Solution:

Step 1: Understand integer division behavior
a / b with Ints does integer division, losing decimals.
Step 2: Convert operands before division
Convert a and b to Float before division to keep decimals. let result = Float(a) / Float(b) does this correctly.
Final Answer:
let result = Float(a) / Float(b) -> Option C
Quick Check:
Convert Ints to Float before dividing [OK]

Quick Trick: Convert Ints to Float before division to keep decimals [OK]
