Another way to compare two values is with the equality operators.

We can use the equality operator (==) to check if the value on the right side of the operator is equal to the value on the left. If the values are equivalent the expression will return true; otherwise, it will return false:

var userPassword = "secret884"
var attemptedPassword = "secret884"

if (userPassword == attemptedPassword) {
  println("The password you entered is correct.")
}

This code snippet will output "The password you entered is correct." because userPassword and attemptedPassword have the same value.

On the other hand, the inequality operator (!=) is used to determine if the values on each side of the != operator are different. This expression returns true when the two values being compared are not equal to each other.

We can use != to check if a gathering of 9 people can evenly split 16 slices of pizza amongst themselves:

var slicesOfPizza = 16
var numPeople = 9

if (slicesOfPizza % numPeople != 0) {
  println("The pizza cannot be split evenly.")
}
// Prints: The pizza cannot be split evenly.

Using modulo %, we can find if dividing 16 by 9 has a remainder of 0. Since the remainder value does not equal 0, "The pizza cannot be split evenly." is outputted to the terminal.
