Trying to do this in C++

Question 4: Implement the function: void oddsKeepEvensFlip (int arr[], int arrSize) This function gets an array of integers arr and its logical size arrSize When called, it should reorder (in-place) the elements of arr so that: 1. All the odd numbers come before all the even numbers 2. The odd numbers will keep their original relative order 3. The even numbers will be placed in a reversed order (relative to their original order). For example, if arr = [5, 2, 11, 7, 6, 4], after calling oddsKeepEvensFlip(arr, 6),arr will be: [5, 11, 7, 4, 6, 2] Implementation requirements 1. Your function should run in linear time. That is, if there are n items in arr, calling oddsKeepEvensFlip (arr, n) will run in (n). Write a main) program that tests this function.. 2
