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 second subscript operator is invalid here. You passed a int * pointer into function, which is a 1-d array. So only one subscript operator can be used on it.

Solution : you can pass int ** pointer into funciton
