multimap::size

public member function
size_type size() const;

Return container size

Returns the number of elements in the container.

Parameters

none

Return Value

// multimap::size
#include <iostream>
#include <map>
using namespace std;
int main ()
{
  multimap<char,int> mymultimap;
  mymultimap.insert(pair<char,int>('x',100));
  mymultimap.insert(pair<char,int>('y',200));
  mymultimap.insert(pair<char,int>('y',350));
  mymultimap.insert(pair<char,int>('z',500));
  cout << "mymultimap.size() is " << (int) mymultimap.size() << endl;
  return 0;
}


Output:
mymultimap.size() is 4

Complexity

Constant.
