size_type max_size() const;
(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.

Contents

Parameters

(none)

Return value

Maximum number of elements.

Exceptions

noexcept specification:  
noexcept
  

Complexity

Constant.

Notes

This value is typically equal to std::numeric_limits<size_type>::max(), and reflects the theoretical limit on the size of the container. At runtime, the size of the container may be limited to a value smaller than max_size() by the amount of RAM available.
