NAME¶

std::array::max_size - std::array::max_size

Synopsis¶

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

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 <locale>
#include <array>

int main()
{
std::array<char, 10> q;
std::cout.imbue(std::locale("en_US.UTF-8"));
std::cout << "Maximum size of the std::array is " << q.max_size() << '\n';
}

Output:¶

Maximum size of the std::array is 10
