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.

(none).

Maximum number of elements.

`noexcept`

specification: `noexcept`

Constant.

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`

).

#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

returns the number of elements (public member function) |
