Example
// std_tr1__unordered_map__unordered_map_pointer.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::iterator it = c1.begin();
it != c1.end(); ++it)
{
Mymap::pointer p = &*it;
std::cout << " [" << p->first << ", " << p->second << "]";
}
std::cout << std::endl;
return (0);
}
[c, 3] [b, 2] [a, 1]
