std::array::max_size(3)

NAME
std::array::max_size - std::array::max_size

Synopsis
   constexpr size_type max_size() const noexcept; (since C++11)
   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 <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:
 10 = 0xA
 10 = 0xA
