constexpr size_type max_size()constnoexcept;		(since C++11)

Returns the maximum number of elements the container is able to hold.

Return value

Maximum number of elements, i.e. N.

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> 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
