	Assigns the value to all elements in the container.

Parameters
	value - the value to assign to the elements

Return value
	(none)

Complexity
	Linear in the size of the container.

Example
     // Run this code

      #include <array>
      #include <cstddef>
      #include <iostream>

      int main()
      {
	  constexpr std::size_t xy = 4;

	  using Cell = std::array<unsigned char, 8>;

	  std::array<Cell, xy * xy> board;

	  board.fill({0xE2, 0x96, 0x84, 0xE2, 0x96, 0x80, 0, 0}); // "aa";

	  for (std::size_t count{}; Cell c : board)
	      std::cout << c.data() << ((++count % xy) ? "" : "\n");
      }

Possible output:
      aaaaaaaa
