multiset upper_bound() in C++ STL with Examples
In this tutorial, we will be discussing a program to understand multiset upper_bound() in C++ STL.
The function upper_bound() returns the pointer to an element which is bigger than the one provided as a parameter, else it returns the pointer to the last element in the container.
Example
#include <bits/stdc++.h>
using namespace std;
int main(){
multiset<int> s;
s.insert(1);
s.insert(3);
s.insert(3);
s.insert(5);
s.insert(4);
cout << "The multiset elements are: ";
for (auto it = s.begin(); it != s.end(); it++)
cout << *it << " ";
auto it = s.upper_bound(3);
cout << "\nThe upper bound of key 3 is ";
cout << (*it) << endl;
it = s.upper_bound(2);
cout << "The upper bound of key 2 is ";
cout << (*it) << endl;
it = s.upper_bound(10);
cout << "The upper bound of key 10 is ";
cout << (*it) << endl;
return 0;
}Output
The multiset elements are: 1 3 3 4 5 The upper bound of key 3 is 4 The upper bound of key 2 is 3 The upper bound of key 10 is 5
