multiset max_size() in C++ STL with Examples
The multiset::max_size() is a built-in function in C++ STL which returns the maximum number of elements a multiset container can hold.
Syntax:
multiset_name.max_size()
Parameters: The function does not accept any parameters.
Return Value: The function returns the maximum number of elements a multiset container can hold.
Below programs illustrate the above function:
Program 1:
// CPP program to demonstrate the // multiset::max_size() function // when multiset is non-empty #include <bits/stdc++.h> using namespace std; int main() { multiset< int > s; // Function to insert elements // in the multiset container s.insert(10); s.insert(13); s.insert(13); s.insert(25); s.insert(24); cout << "The multiset elements are: " ; for ( auto it = s.begin(); it != s.end(); it++) cout << *it << " " ; cout << "\nThe max size of multiset: " << s.max_size(); return 0; } |
Output:
The multiset elements are: 10 13 13 24 25 The max size of multiset: 461168601842738790
Program 2:
// CPP program to demonstrate the // multiset::max_size() function // when multiset is empty #include <bits/stdc++.h> using namespace std; int main() { multiset< int > s; cout << "\nThe max size of multiset: " << s.max_size(); return 0; } |
Output:
The max size of multiset: 461168601842738790
