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

Contents

[edit] Parameters

(none)

[edit] Return value

Maximum number of elements.

[edit] Exceptions

noexcept specification:  
noexcept
  

[edit] Complexity

Constant.

[edit] 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)

[edit] Example

#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
