 // =============> write your explanation here
-// the function does not get any "define parameter", like nothing, so it tries to the "num" in global variable
-// that is given just before the function that is const num = 103;
-// so, every time that function is called, it will use num 103 as parameter
-
 // 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
-// no syntax error just logic error :) because, sometime we need to manipulate the function just like that. BTW that is not save anyway.
