std::array<T,N>::max_size (3) - Linux Manuals

std::array<T,N>::max_size: std::array<T,N>::max_size

NAME

std::array<T,N>::max_size - std::array<T,N>::max_size

Synopsis

constexpr size_type max_size() noexcept; (since C++11)
                                                (until C++14)
constexpr size_type max_size() const noexcept; (since C++14)

Returns the maximum number of elements the container is able to hold due to system or library implementation limitations, i.e. std::distance(begin(), end()) for the largest container.

Parameters

(none)

Return value

Maximum number of elements.

Complexity

Constant.

Notes

Because each std::array<T, N> is a fixed-size container, the value returned by max_size equals N (which is also the value returned by size)

Example

// Run this code

  #include <iostream>
  #include <array>

  int main()
  {
      std::array<char, 10> s;
      std::cout << "Maximum size of a 'array' is " << s.max_size() << "\n";
  }

Possible output:

  Maximum size of a 'array' is 10
