C subscripted value is neither array nor pointer nor vector when assigning an array element value

Question

Sorry for asking the already answered question, I am a newbie to C and don\'t understand the solutions. Here is my function

int rotateArr(int *arr) {
    int         


        

Answer 1

The problem is that arr is not (declared as) a 2D array, and you are treating it as if it were 2D.
