Difference between std::set and std::list

// C++ program to demonstrate the
// working of set in c++
#include <bits/stdc++.h>
using namespace std;

// Driver code
int main()
{
    // Declaring a set
    set<int> s;

    // Inserting elements
    // into the set
    s.insert(10);
    s.insert(5);
    s.insert(15);
    s.insert(1);

    // Insert the duplicate elements
    s.insert(1);

    cout << "Elements in set:\n";

    // Print the element stored in set
    for (auto it : s)
        cout << it << " ";

    return 0;
}

// C++ program to demonstrate the
// working of list in cpp
#include <bits/stdc++.h>
using namespace std;

// Driver code
int main()
{
    // Declaring a list
    list<int> l;

    // Inserting elements
    // in the list
    l.push_back(10);
    l.push_back(15);
    l.push_back(5);
    l.push_back(1);
    l.push_back(1);
    l.push_back(10);

    cout << "Elements in list:\n";

    // Print the elements of list
    for (auto it : l)
        cout << it << " ";

    return 0;
