@EllaHa @petraBT can we add 2 more questions to make it creschedo ? like:

1/ Suppose we have made the following declarations:

    int arr[3] = {3, 2, 1};
    int * ptr = arr;
    * ptr = 1; 
    * (arr+ 1) = 2; 
    * (ptr + 2) = 3;

what is the value of: arr[0] ? arr[1] ? arr[2] ?

And

2/ 1/ Suppose we have made the following declarations:

    int arr[2] = {3, 2};
    int * ptr = arr;
    int * ptr2 = ptr + 1;
    * (ptr2 - 1) = 2; 
    * (ptr + 1) = 3;

what is the value of: arr[0] ? arr[1] ?

[petraBT]

Sure, that sounds good! Is there a way for the learner to get feedback on those two questions first though, before attempting the next ones? Otherwise, how does this help?

[Kitkatniss]

please write ; crescendo

[Kitkatniss]

I do agree with Petra for the feedback after the two first questions.

Some testers suggested to add autocorrected exercices for pointers. Just to pratice more...

I am afraid we can't add any change like this at this stage. This has to be kept as improvement for the next course session.
