Swift - Operators and Expressions

Identify the error in this Swift code:

let a: UInt8 = 250
let b: UInt8 = 10
let c = a + b

APossible overflow without using &+ operator

BIncorrect variable types for addition

CMissing semicolon after let c

DUsing + instead of - operator

Step-by-Step Solution

Solution:

Step 1: Check addition of UInt8 values
Adding 250 + 10 exceeds UInt8 max 255, causing overflow.
Step 2: Identify missing overflow operator
Using + causes runtime error on overflow; &+ should be used to allow wrapping.
Final Answer:
Possible overflow without using &+ operator -> Option A
Quick Check:
UInt8 addition overflow needs &+ [OK]

Quick Trick: Use &+ for addition that may overflow UInt8 [OK]
