 // Predict the output of the following code:
 // =============> Write your prediction here
+// Answer below:
+// There is a constant variable num with value 103, the code should print last digit of the constant variable.
 
-const num = 103;
+// const num = 103;
 
-function getLastDigit() {
-  return num.toString().slice(-1);
-}
+// function getLastDigit() {
+//   return num.toString().slice(-1);
+// }
 
-console.log(`The last digit of 42 is ${getLastDigit(42)}`);

+// 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
+// Answer below:
+// 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
+// Answer below:
+// The code kept repeating same value for all log because of the constant variable decleared before the function and used inside the function.
+
 // Finally, correct the code to fix the problem
 // =============> write your new code here

 // This program should tell the user the last digit of each number.
 // Explain why getLastDigit is not working properly - correct the problem
+// The global constant variable outside the function has affected the code and caused it to always reference the last number of the global variable
+// To fix this, the global variable will be removed from code and the function getLastDigit should take the variable name "num" assigned to the global variable.
