Day 2 checkpoint

Forums > 100 Days of SwiftUI

Hi all,

I am having problems with the day 2 checkpoint. it seems to complex for me to understand in my second day. could someone help me with the correct code (as simple as it can get) so I can look at it?

import Cocoa

let fellowship = ["Frodo", "Sam", "Pippin", "Merry", "Gandalf", "Aragorn", "Legolas", "Gimli", "Boromir", "Frodo", "Sam", "Gollum"]

// Making a set of the array removes duplicates because Sets can't have duplicates
let uniqueFellowship = Set(fellowship)

// Printing the number of elements in the array fellowship
print(fellowship.count)

// Printing the number of elements in the set uniqueFellowship
print(uniqueFellowship.count)

let lettersArray = ["A", "A", "B", "A", "C", "D", "A"]
print(lettersArray.count)
// Prints - 7

// Making a set of the array removes duplicates because Sets can't have duplicates
let uniqueLettersArray = Set(lettersArray)

print(uniqueLettersArray.count)
// Prints - 4

print(uniqueLettersArray)
// Prints - ["A", "C", "B", "D"]

weird! thats not the day 2 i am trying to do. my checkpoint-test is about celcius and fahrenheit converter.

Ah sorry, I read checkpoint 2 instead of day 2 checkpoint

import Cocoa

//Create a constant holding any temperature in Celsius
let celsius = 30.0

//Convert that to Fahrenheit by multiplying by 9, dividing by 5, then adding 32
let fahrenheit = ((celsius * 9) / 5) + 32

//Print the results for the user, showing both the Celsius and Fahrenheit values
print("Degrees Fahrenheit: \(fahrenheit)° F")
print("Degress Celsius: \(celsius)° C")

//Convert it back bonus
let convertedBackToCelsius = ((fahrenheit - 32) * 5) / 9
print("Degress Celsius: \(convertedBackToCelsius)° C")
