Courses Plus Student 2,263 PointsI think Im getting an error because of my Incrementing, pleas help!
I tried this code in Xcode and the "initialScore" and "totalScore" values were the same, just like the directions said. Is it some sort of silly syntax? Please help!
// Enter your code below
var initialScore = 8
initialScore = ++initialScore
let totalScore = initialScore

You don't have to assign the incremented value back to the variable storing that value. The ++ operator will update the value stored in that variable.
If you use the prefix ++ operator, the value of initialScore (which starts as 8), will be incremented to a value of 9. This new value will then be assigned to the constant totalScore.
// Enter your code below
var initialScore = 8
let totalScore = ++initialScore
It's important to note that the prefix ++ and postfix ++ operator, as well as its counterpart -- operator, will not be supported in Swift 3.0. The correct way to do this will be:
var initialScore = 8
initialScore += 1
let totalScore = initialScore
Yes this does require an extra line of code, however, the Swift community believes this approach to be clearer.
Good Luck
