unordered_multiset bucket() function in C++ STL

Last Updated : 02 Aug, 2018

The

is a built-in function in C++ STL which returns the bucket number in which a given element is. Bucket size varies from 0 to

unordered_multiset_name.bucket(element)

The function accepts a single mandatory

which specifies the value whose bucket number is to be returned.

It returns an unsigned integral type which signifies the bucket number in which the element is. Below programs illustrates the above function:

// C++ program to illustrate the
// unordered_multiset::bucket() function
#include <bits/stdc++.h>
using namespace std;

int main()
{

    // declaration
    unordered_multiset<int> sample;

    // inserts element
    sample.insert(10);
    sample.insert(15);
    sample.insert(15);
    sample.insert(13);
    sample.insert(13);

    for (auto it = sample.begin(); it != sample.end(); it++) {
        cout << "The bucket number in which " << *it
             << " is " << sample.bucket(*it) << endl;
    }
    return 0;
}

The bucket number in which 13 is 6
The bucket number in which 13 is 6
The bucket number in which 10 is 3
The bucket number in which 15 is 1
The bucket number in which 15 is 1

// C++ program to illustrate the
// unordered_multiset::bucket() function
#include <bits/stdc++.h>
using namespace std;

int main()
{

    // declaration
    unordered_multiset<char> sample;

    // inserts element
    sample.insert('a');
    sample.insert('a');
    sample.insert('b');
    sample.insert('b');
    sample.insert('c');
    sample.insert('c');
    sample.insert('e');

    for (auto it = sample.begin(); it != sample.end(); it++) {
        cout << "The bucket number in which " << *it
             << " is " << sample.bucket(*it) << endl;
    }
    return 0;
}

The bucket number in which e is 16
The bucket number in which a is 12
The bucket number in which a is 12
The bucket number in which b is 13
The bucket number in which b is 13
The bucket number in which c is 14
The bucket number in which c is 14
