utx::iota

utx::iota

utx::iota is a function object of class used to generate auto incremental values to a range.

Different with std::iota: utx::iota can take the range name as its parameter, without begin/end.

Different with std::ranges::iota: utx::iota accepts floating point and some more data types, not limited by std::iter_difference_t.

int main()

	utx::iota(v1, -5);
	utx::print(v1);
// -5 -4 -3 -2 -1 0 1 2 3 4 5

	std::vector<utx::fx32> v2(4);

	utx::iota(v2.begin(), v2.end(), 1.4f);
