With arrays, why is it the case that a[5] == 5[a]?
...ge would make some situations associative which presently aren't, e.g. 3U+(UINT_MAX-2L) would equal (3U+UINT_MAX)-2. What would be best, though, is for the language to have add new distinct types for promotable integers and "wrapping" algebraic rings, so that adding 2 to a ring16_t which holds 6553...

Why does integer division in C# return an integer and not a float?
...t has the first of these types in which its value can be represented: int, uint, long, ulong.
Thus, since you declare 13 as integer, integer division will be performed:

How do I find the length of an array?
...td container or a C-style array. For example:
#include <iterator>
uint32_t data[] = {10, 20, 30, 40};
auto dataSize = std::size(data);
// dataSize == 4
