[edit] Example
 The following code uses size to display the number of elements in a std::unordered_multiset<int>:
 
Run this code
#include <unordered_set> #include <iostream> int main() { std::unordered_multiset<int> nums {1, 3, 5, 7}; std::cout << "nums contains " << nums.size() << " elements.\n"; }
Output:
nums contains 4 elements.
