### [edit] Parameters

(none)

### [edit] Return value

The number of elements in the container.

### [edit] Exceptions

(none) | (until C++11)
`noexcept` specification: noexcept | (since C++11)

### [edit] Example

[edit]

The following code uses `size` to display the number of elements in a std::multiset:

Run this code

    #include <set>
    #include <iostream>

    int main()
    {
        std::multiset<int> nums {1, 3, 5, 7};

        std::cout << "nums contains " << nums.size() << " elements.\n";
    }

Output:

    nums contains 4 elements.
