LESSON 158 OF 415 · LOOPING OVER ARRAY INDICES

Employee of the Year V4 - Project in Swift

Practice

A whole team is competing. Use a for loop over the arrays to find the most productive employee, then print their 15% bonus.

You start with:

        let names = ["John Doe", "Mary Jane", "Bob Smith", "Alice Chen", "Carlos Diaz"]
        let productivities = [83, 133, 97, 150, 120]
        let salaries = [135000, 335000, 210000, 250000, 180000]

Build:

Alice Chen
Bonus: $37500

Rules:

Index i in all three arrays refers to the same employee.
The winner is whichever employee has the highest productivity. If two employees share the highest productivity, the one listed first wins.
The winner's bonus is 15% of their salary, rounded down to a whole number.
Print the winner's name on the first line, then "Bonus: $<amount>" on the second.

Start with var bestIndex = 0 and loop over the other indices with for i in 1..<names.count. Inside the loop, update the best index only when productivities[i] > productivities[bestIndex]: a strict comparison keeps the first employee on a tie.

Dividing two whole numbers (Int) drops the fraction, so salaries[bestIndex] * 15 / 100 is already rounded down: let bonus = salaries[bestIndex] * 15 / 100

Convert the number with String(...) (or use \(...) inside the text): print("Bonus: $" + String(bonus))

        let names = ["John Doe", "Mary Jane", "Bob Smith", "Alice Chen", "Carlos Diaz"]
        let productivities = [83, 133, 97, 150, 120]
        let salaries = [135000, 335000, 210000, 250000, 180000]

        var bestIndex = 0
        for i in 1..<names.count {
            if productivities[i] > productivities[bestIndex] {
                bestIndex = i
            }
        }
        let bonus = salaries[bestIndex] * 15 / 100
        print(names[bestIndex])
        print("Bonus: $" + String(bonus))
