Comment

// CPP program to illustrate using
// std :: upper_bound with vectors
#include <bits/stdc++.h>

// Driver code
int main()
{
	std::vector<int> v{ 10, 20, 30, 40, 50 };

	// Print vector
	std::cout << "Vector contains :";
	for (int i = 0; i < v.size(); i++)
		std::cout << " " << v[i];
	std::cout << "\n";

	std::vector<int>::iterator upper1, upper2;

	// std :: upper_bound
	upper1 = std::upper_bound(v.begin(), v.end(), 35);
	upper2 = std::upper_bound(v.begin(), v.end(), 45);

	std::cout << "\nupper_bound for element 35 is at position : "
			<< (upper1 - v.begin());
	std::cout << "\nupper_bound for element 45 is at position : "
			<< (upper2 - v.begin());

	return 0;
}

It returns an iterator pointing to the first 
element in the range [first, last) that is greater than value, 
or last if no such element is found. 


upper_bound( arr,arr+n,data);

lower bound and upper bound in c++

Comment

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

int main(){
    int n;cin>>n;
    vector<int>v;

    for(int i=0;i<n;i++){
        cin>>v[i];
    }
    sort(v.begin(),v.end());


    //lower bound for vector
    auto pointer1 = lower_bound(v.begin(), v.end(), 7);
    cout<<(*pointer1)<<endl;

    //lower bound for array;
    int array[n];
    for(int i=0;i<n;i++){
        cin>>array[i];
    }
    sort(array,array+n);
    //lowerbound
    int *pointer2 = lower_bound(array, array+n, 7);

    //if you want upper bound then just replace lower_bound with upper_bound
}
