 // Predict the output of the following code:

 // Now run the code and compare the output to your prediction
 // =============> write the output here
-// nope.. It runs as predicted :) xixixiixi... that way we are in this "debugging" session.
-// it runs but no syntax error but the output are not correct.
-
 // Explain why the output is the way it is
 // =============> 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
-const num = 103;

 // This program should tell the user the last digit of each number.

-// no syntax error just logic error :) because, sometime we need to manipulate the function just like that. BTW that is not save anyway.
