You can fill out two arrays with odd, even numbers like this
var evenArray = new int[10];
var oddArray = new int[10];
for (int i = 0, even = 0; i < evenArray.Length; i++, even += 2)
{
evenArray[i] = even;
}
for (int i = 0, odd = 1; i < oddArray.Length; i++, odd += 2)
{
oddArray[i] = odd;
}
Produces
evenArray = [ 0, 2, 4, 6, 8, 10, 12, 14, 16, 18 ]
oddArray = [ 1, 3, 5, 7, 9, 11, 13, 15, 17, 19 ]
