# std::deque::max_size

From cppreference.com
< cpp‎ | container‎ | deque

[edit template]

size_type max_size() const; |  |

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.

### [edit] Parameters

(none)

### [edit] Return value

Maximum number of elements.

### [edit] Exceptions

(none) | (until C++11)
`noexcept` specification: noexcept | (since C++11)

### [edit] Complexity

Constant.

### [edit] 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.
