      constexpr size_type max_size()constnoexcept;
      (since C++11)

      Returns the maximum number of elements the container is able to hold.

      Contents

      [edit]Return value

      Maximum number of elements, i.e.N.

      [edit]Complexity

      Constant.

      [edit]Notes

      Because eachstd::array<T, N> is a fixed-size container, the value returned bymax_size equalsN (which is also the value returned bysize()).

      [edit]Example

      Run this code
      #include <iostream>#include <locale>#include <array> int main(){std::array<char,10> p;std::array<long,10> q; std::cout.imbue(std::locale("en_US.UTF-8"));std::cout<<std::uppercase<<"p.max_size() = "<<std::dec<< p.max_size()<<" = 0x"<<std::hex<< p.max_size()<<'\n'<<"q.max_size() = "<<std::dec<< q.max_size()<<" = 0x"<<std::hex<< q.max_size()<<'\n';}

      Output:

      p.max_size() = 10 = 0xAq.max_size() = 10 = 0xA
