// Predict and explain first...

// Predict the output of the following code:
// =============> Write your prediction here: The function getLastDigit doesn't take any parameters, so it will always return the last digit of the number 103, 3.

const num = 103;

function getLastDigit() {
  return num.toString().slice(-1);
}

console.log(`The last digit of 42 is ${getLastDigit(42)}`);
console.log(`The last digit of 105 is ${getLastDigit(105)}`);
console.log(`The last digit of 806 is ${getLastDigit(806)}`);

// Now run the code and compare the output to your prediction
// =============> write the output here: The last digit of 42 is 3. The last digit of 105 is 3. The last digit of 806 is 3
// Explain why the output is the way it is
// =============> write your explanation here: The function getLastDigit doesn't take any parameters, so it always returns the last digit of the variable num, which is 103.
// Finally, correct the code to fix the problem
// =============> write your new code here:
// function getLastDigit(num) {
//   return num.toString().slice(-1);
// }

// console.log(`The last digit of 42 is ${getLastDigit(42)}`);
// console.log(`The last digit of 105 is ${getLastDigit(105)}`);
// console.log(`The last digit of 806 is ${getLastDigit(806)}`);

// This program should tell the user the last digit of each number.
// Explain why getLastDigit is not working properly - correct the problem
// The function getLastDigit is not working properly because it does not take any parameters, so it always returns the last digit of the variable num, which is 103.
