Set find() function in C++ STL

Set find() function in C++ STL returns an iterator to the element which is searched in the set container. The iterator points to the position just after the last element in the set, if the element is not found.

Algorithm

Begin
   Define function printS() to print elements of set container.
   initialize an empty set container s. Insert some elements in s
   set container. Call function to print elements of set container.
   Call the set find() function to find an element from s set container.
   If element is in the set then
      Print elememt is in the set.
   Else
      Print element is not in the set. 
End.

Example Code

Live Demo

#include<iostream>
#include <bits/stdc++.h>
using namespace std;
int main() {
   set<int> s;
   set<int>::iterator it;
   s.insert(7);
   s.insert(6);
   s.insert(1);
   s.insert(4);
   s.insert(2);
   s.insert(9);
   s.insert(10);
   auto pos = s.find(6);
   cout << "The set elements after 6 are: ";
   for ( it = pos; it != s.end(); it++)
      cout << *it << " ";
   return 0;
