1,594 PointsI am having trouble with a comparison operator challenge
How do I find the results for the comparison operator?
// Enter your code below
var initialScore = 8
initialScore += 1
let comparisonOperation: Int = !10
let isWinner = 9

8,386 PointsHi Heather,
This one is a little odd at first, but here is the solution:
var initialScore = 8
initialScore += 1
let isWinner = initialScore != 10
Best way to explain it is that "isWinner" will equal the result of the initialScore comparison. The comparison will resolve to either true or false. That is, intialScore != 10 will return true or false depending on the value of initialScore. Since initialScore is 9, the return value for "isWinner" will be true (boolean).
