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.
Parameters
(none).
Return value
Maximum number of elements.
Exceptions
noexcept
specification: noexcept
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
#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
