558 PointsHow to use increment operation to increase a number
I am required to add 1 to initialScore and assign the result to totalScorel using increment operation. And initialScore should be equal to totalScore after increment operation. My code likes fine, but I don't know why it cannot pass the quiz. Is there anyone help me to figure out this problem? Thank you so much!
// Enter your code below
var initialScore = 8
var totalScore = 0
totalScore = initialScore++

14,175 PointstotalScore must be a constant and you must increment before not after.
let totalScore = ++initialScore

14,175 PointsThe challenge wants the unary increment operator before. If the unary increment operator is after than totalScore = 8. I'm use to using the unary increment after, but in this case they want it before.

558 PointsBut I will get the different result if put the increment before initialScore.
This is what the task I need to do:
Let's assume we're creating a silly game. In this game every time a user completes an objective (whatever it is) we increment their total score by 1 point.
In the editor below, initialScore is the players current score. Assuming they completed a single objective for this level, let's add 1 point to their score using the increment operator and assign the result to a constant named totalScore.
Remember that the position of the unary increment operator matters. For this task to pass, we want both totalScore and initialScore to have the same value after the increment operation.
