std::flat_multiset<Key,Compare,KeyContainer>::max_size

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( ) )

Parameters

(none)

Return value

Maximum number of elements.

Complexity

Constant.

Notes

This value typically reflects the theoretical limit on the size of the container, at most std::numeric_limits <difference_type> :: max ( ) . At runtime, the size of the container may be limited to a value smaller than max_size()

Example

#include <iostream>
#include <flat_set>
#include <locale>
 
int main()
{
    std::flat_multiset<char> q;
    std::cout.imbue(std::locale("en_US.UTF-8"));
    std::cout << "Maximum size of a std::flat_multiset is " << q.max_size() << '\n';
}

Maximum size of a std::flat_multiset is 768,614,336,404,564,650
