use of algorithms in function cause ERROR: no instance of overloaded function

I don't understand what you're trying to do in bool_element_option_03() above. You seem to be trying to access a 2-d array as a 1-d array??

If yes, then something like:

 void bool_element_option_03(const int(&arr_value)[ELEMENTS], int(&arr_copy_value)[ELEMENTS], int(&arr_elements)[ELEMENTS][SLOTS]) {
	std::copy(std::begin(arr_value), std::end(arr_value), std::begin(arr_copy_value));
	std::sort(std::rbegin(arr_copy_value), std::rend(arr_copy_value));

	const auto it { (int*)&arr_elements };

	for (size_t i {}, ie { ELEMENTS * SLOTS }; i < ie; ++i)
		std::cout << it[i] << ' ';
	    // std::cout << *(it + i) << ' ';

	std::cout << '\n';

	std::cout << "\nReverse sorted:\n";
	show(arr_copy_value);
}

or:

const auto* it { (int*)&arr_elements };

	for (size_t i {}, ie { ELEMENTS * SLOTS }; i < ie; ++i, ++it)
		std::cout << *it << ' ';

but this is 'c' like code and not considered 'good' C++ code.

Also note that this memory 'hack' for treating a 2d-array as a 1-d isn't valid for std::vector and std::array.
