void clear( );
Example
// multiset_clear.cpp
// compile with: /EHsc
#include <set>
#include <iostream>
int main( )
{
using namespace std;
multiset <int> ms1;
ms1.insert( 1 );
ms1.insert( 2 );
cout << "The size of the multiset is initially "
<< ms1.size( ) << "." << endl;
ms1.clear( );
cout << "The size of the multiset after clearing is "
<< ms1.size( ) << "." << endl;
}
The size of the multiset is initially 2. The size of the multiset after clearing is 0.
