std::array::max_size
From cppreference.com
| 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
