examples: avoid warning when iterating over index entries

When iterating over index entries, we store the indices in an unsigned
int. As the index entrycount is a `size_t` though, this may be a loss of
precision which a compiler might rightfully complain about.

Use `size_t` instead to fix any warnings.
