find()C ++ STL中的Set函数将迭代器返回到在set容器中搜索的元素。如果找不到该元素,则迭代器指向紧接集合中最后一个元素的位置。
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.
#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;
}输出结果
The set elements after 6 are: 6 7 9 10
