Why the "non"? Shouldn't the name be "address_of_first_array_elem"? How is this different from std::begin(lhs)?
No. The motivating use case for this were built-in multidimensional arrays. I wanted a generic way to compare and copy them without resorting to nested loops.
For example:
typedef int ArrType[2][3];
ArrType a1 = { {0, 1, 2}, {3, 4, 5} }; ArrType a2 = { {0, 1, 2}, {3, 4, 5} };
// Prints 0. std::cout << "Std Equal: " << std::equal(a1, a1 + 2, a2) << "\n"; // Prints 1. Obviously address_of_first_nonarray_elem would be used instead of subscripting. std::cout << "Flattened Std Equal: " << std::equal(a1[0], a1[0] + 6, a2[0])
Ok, I got it now. The name is not very illuminating, maybe flat_begin/flat_end or a flat_view with begin/end/size would do better.
+1 for flat_view Regards, Kris
