The type of an element.

Remarks
The type describes an element of the controlled sequence.
Example
// std_tr1__unordered_set__unordered_set_value_type.cpp
// compile with: /EHsc
#include <unordered_set>
#include <iostream>
typedef std::unordered_set<char> Myset;
int main()
{
Myset c1;
c1.insert('a');
c1.insert('b');
c1.insert('c');
// display contents " [c] [b] [a]"
for (Myset::const_iterator it = c1.begin();
it != c1.end(); ++it)
std::cout << " [" << *it << "]";
std::cout << std::endl;
// add a value and reinspect
Myset::key_type key = 'd';
Myset::value_type val = key;
c1.insert(val);
for (Myset::const_iterator it = c1.begin();
it != c1.end(); ++it)
std::cout << " [" << *it << "]";
std::cout << std::endl;
return (0);
}
[c] [b] [a] [d] [c] [b] [a]
