multiset max_size() in C++ STL with Examples

// CPP program to demonstrate the
// multiset::max_size() function
// when multiset is non-empty
#include <bits/stdc++.h>
using namespace std;
int main()

    // 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;
