| constexpr size_type max_size() const noexcept; |
(since C++11) | |
Returns the maximum number of elements the container is able to hold.
Contents |
[edit] Parameters
(none)
[edit] Return value
Maximum number of elements, i.e. N.
[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
Run this code
#include <iostream> #include <locale> #include <array> int main() { std::array<char, 10> p; std::array<long, 10> q; std::cout.imbue(std::locale("en_US.UTF-8")); std::cout << std::uppercase << "p.max_size() = " << std::dec << p.max_size() << " = 0x" << std::hex << p.max_size() << '\n' << "q.max_size() = " << std::dec << q.max_size() << " = 0x" << std::hex << q.max_size() << '\n'; }
Output:
p.max_size() = 10 = 0xA q.max_size() = 10 = 0xA
