iOS repl.it - Constants Challenge Solution

constants.swift

//Write your code here.

// Solution
let secondsInAnHour = 3600

// alternatively:
// let secondsInAnHour: Int = 3600

// Note, constants can only be set once and cannot be assigned a new value. 
// The below does not work, because it is a constant and thus cannot be changed.
// secondsInAnHour = 1337



//Don't change the code below.
print(secondsInAnHour)

hey @TheMuellenator was this a trick question? Is it as simple of let secondsInAnHour = 3600?

I thought we had to select one of the seconds in the hour. Just double checking!

Yes, very easy! Didn't expect so solution...

WTH is the solution, it makes no sense...

"This does not work, because it is a constant and thus cannot be changed"??????

weren't we meant to declare it as a constant?

Solution with type-checking

let secondsInAnHour: Int = 3600
print(secondsInAnHour)

hahaha Github trying to make my code wrong. that's why screenshot:

I thought it had to be something a little bit more complicated, like with some sort of math equation LOL

There are many ways to complete this challenge. I used this code below and passed:

let sencondInAnHour = Int(3600)

please mullenator.can u please explain the question. i am not getting what is the question

Hi! What if I write var instead of let?

Hi! What if I write var instead of let?

It will work, But no mean to use var keywords for constants (as it was immutable value).

• Use var for variables
• Use let for constants

func exercise() {
//Write your code here.

let secondsInAnHour: Int = 3600

//Don't change the code below.
print(secondsInAnHour)

}

LOL! Only here did I realize that I was wasting all this time adding minutes rather than seconds in the hour! 🤣🤦‍♂️

My solution:

let secondsInAnHour: Int = 60*60

//Don't change the code below.
print(secondsInAnHour)

func exercise() {

let secondsInAnHour = 60 * 60

print(secondsInAnHour)

}

This was a straight forward answer, I even looked for some tricks too

var hour = 1;
var min = 60
var sec = 60

let secondsInAnHour = hour * min * sec;

print(secondsInAnHour);

let secondsInAnHour = 3600

print(secondsInAnHour)

let secondsInAnHour = 60 * 60

print(secondsInAnHour)
