unordered_map::cend
Designates the end of the controlled sequence.
const_iterator cend() const;
Remarks
The member function returns a const forward iterator that points just beyond the end of the sequence.
Example
// std_tr1__unordered_map__unordered_map_cend.cpp
// compile with: /EHsc
#include <unordered_map>
#include <iostream>
typedef std::unordered_map<char, int> Mymap;
int main()
{
Mymap c1;
c1.insert(Mymap::value_type('a', 1));
c1.insert(Mymap::value_type('b', 2));
c1.insert(Mymap::value_type('c', 3));
// display contents " [c 3] [b 2] [a 1]"
for (Mymap::const_iterator it = c1.cbegin();
it != c1.cend(); ++it)
std::cout << " [" << it->first << ", " << it->second << "]";
std::cout << std::cendl;
// inspect last two items " [a 1] [b 2]"
Mymap::const_iterator it2 = c1.cend();
--it2;
std::cout << " [" << it2->first << ", " << it2->second << "]";
--it2;
std::cout << " [" << it2->first << ", " << it2->second << "]";
std::cout << std::cendl;
return (0); }
[c, 3] [b, 2] [a, 1] [a, 1] [b, 2]
