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) |
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)
