set operator = in C++

operator =: This is an operator to assign values. Set list assignment operator.

Parameters:

 __l – An initializer_list. 

This function fills a set with copies of the elements in the initializer list __l. 

Note that the assignment completely changes the set and that the resulting set's size is the 

same as the number of elements assigned.

Syntax:

st = {__l}

For Example:

st ={3,2,1,4}

Approach

C++

#include <bits/stdc++.h>
using namespace std;

int main()
{
    set<int> st;

    st = {3, 2, 1, 4};

    for (auto it = st.begin(); it != st.end(); it++)
        cout << *it << " ";

    return 0;
}
