c++ Please explain why its wrong.

The findDisorder function is supposed to find the first item in an array that is less than the element preceding it, and set the p parameter to point to that item, so the caller can know the location of that item. Explain why this function won't do that, and show how to fix it. Your fix must be to the function only; you must not change the the main routine below in any way, yet as a result of your fixing the function, the main routine below must work correctly. void findDisorder(int arr[], int n, int* p) { for (int k = 1; k < n; k++) { if (arr[k] < arr[k-1]) { p = arr + k; return; } } p = nullptr; } int main() { int nums[6] = { 10, 20, 20, 40, 30, 50 }; int* ptr; findDisorder(nums, 6, ptr); if (ptr == nullptr) cout << "The array is ordered" << endl; else { cout << "The disorder is at address " << ptr << endl; cout << "It's at index " << ptr - nums << endl; cout << "The item's value is " << *ptr << endl; } return 0; }
