std::multiset::max_size
From cppreference.com
| 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.
Parameters
(none)
Return value
Maximum number of elements.
Exceptions
| (none) | (until C++11) |
noexcept specification: noexcept |
(since C++11) |
Complexity
Constant.
Notes
This value typically 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.
Example
Run this code
#include <iostream> #include <set> int main() { std::multiset<char> s; std::cout << "Maximum size of a 'multiset' is " << s.max_size() << "\n"; }
Possible output:
Maximum size of a 'multiset' is 18446744073709551615
