Example

// std_tr1__unordered_set__unordered_multiset_bucket_size.cpp 
// compile with: /EHsc 
#include <unordered_set> 
#include <iostream> 
 
typedef std::unordered_multiset<char> Myset; 
int main() 
    { 
    Myset c1; 
 
    c1.insert('a'); 
    c1.insert('b'); 
    c1.insert('c'); 
 
// display contents " [c] [b] [a]" 
    for (Myset::const_iterator it = c1.begin(); 
        it != c1.end(); ++it) 
        std::cout << " [" << *it << "]"; 
    std::cout << std::endl; 
 
// display buckets for keys 
    Myset::size_type bs = c1.bucket('a'); 
    std::cout << "bucket('a') == " << bs << std::endl; 
    std::cout << "bucket_size(" << bs << ") == " << c1.bucket_size(bs) 
        << std::endl; 
 
    return (0); 
    } 
 

 [c] [b] [a]
bucket('a') == 7
bucket_size(7) == 1
