std::flat_set::max_size(3) | C++ Standard Libary | std::flat_set::max_size(3) |
NAME¶
std::flat_set::max_size - std::flat_set::max_size
Synopsis¶
size_type max_size() const noexcept; (since C++23)
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¶
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() by the amount of
RAM
available.
Example¶
// Run this code
#include <iostream>
#include <flat_set>
#include <locale>
int main()
{
std::flat_set<char> q;
std::cout.imbue(std::locale("en_US.UTF-8"));
std::cout << "Maximum size of a std::flat_set is " <<
q.max_size() << '\n';
}
Possible output:¶
Maximum size of a std::flat_set is 768,614,336,404,564,650
