iOS Swift 2.0 Basics Swift Operators Working With Operators: Part 2

Comparison Operation

I don't understand what I'm doing wrong.

operators2.swift
// Enter your code below

var initialScore = 8
initialScore = initialScore + 1
var totalScore = initialScore
totalScore = initialScore++
totalScore < 10
let isWinner = 9
isWinner < totalScore

Hi there,

For this, you start with the initialScore variable defined. You then want to increment that, and store the result in a constant named totalScore. Ue the ++ operator for that and put that before the variable name. Assign that to totalScore which is a constant, declared using let:

var initialScore = 8
let totalScore = ++initialScore

Next, you want to compare totalScore to 10. The result of that comparison needs to be stored in a constant called isWinner. You want to compare that totalScore is not 10, using the != operator and assign that comparison into the isWinner constant:

let isWinner = totalScore != 10

I hope that helps,

Steve.

Thanks a lot.

No problem! :+1:
