 // Explain why the output is the way it is
 // =============> write your explanation here
+// The output is the way it is because the function getLastDigit does not take any parameters and always uses the global variable num which is set to 103. So all the function calls return the same result.
 // Finally, correct the code to fix the problem
 // =============> write your new code here
