How do you separate an even and odd array?

Explanation

1. First, declare your int array.
2. Run a for loop from i = 0 to i = size to iterate through the array.
3. If the element is an even number, skip it.
4. If the element is an odd number, run another for loop inside the first loop.
5. If the subsequent element is an even number, swap it with the current element.
