map::end
Returns the past-the-end iterator.
const_iterator end( ) const;
iterator end( );
Return Value
The past-the-end iterator. If the map is empty, then map::end() == map::begin().
Remarks
end is used to test whether an iterator has passed the end of its map.
The value returned by end should not be dereferenced.
Example
// map_end.cpp
// compile with: /EHsc
#include <map>
#include <iostream>
int main( )
{
using namespace std;
map <int, int> m1;
map <int, int> :: iterator m1_Iter;
map <int, int> :: const_iterator m1_cIter;
typedef pair <int, int> Int_Pair;
m1.insert ( Int_Pair ( 1, 10 ) );
m1.insert ( Int_Pair ( 2, 20 ) );
m1.insert ( Int_Pair ( 3, 30 ) );
m1_cIter = m1.end( );
m1_cIter--;
cout << "The value of the last element of m1 is:\n"
<< m1_cIter -> second << endl;
m1_Iter = m1.end( );
m1_Iter--;
m1.erase ( m1_Iter );
// The following 2 lines would err because the iterator is const
// m1_cIter = m1.end ( );
// m1_cIter--;
// m1.erase ( m1_cIter );
m1_cIter = m1.end( );
m1_cIter--;
cout << "The value of the last element of m1 is now:\n"
<< m1_cIter -> second << endl;
}
The value of the last element of m1 is: 30 The value of the last element of m1 is now: 20
