Return container size
Returns the number of elements in the container.
Parameters
none
Return Value
The number of elements that conform the
multimap's content.
Member type size_type is an unsigned integral type.
Example
// 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;
}
