Iterating one dimension array as two dimension array

Question

I have,

int[10] oneDim = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}, index = 0;

as shown here, we create the the two dimensional one from the origin.

Answer 1

The two numbers you're showing could be computed, in the order you're showing them in, as index/2 and index%2 respectively. Is that what you mean by "the issue"?
