Example

// std_tr1__unordered_map__unordered_map_max_size.cpp 
// compile with: /EHsc 
#include <unordered_map> 
#include <iostream> 
 
typedef std::unordered_map<char, int> Mymap; 
int main() 
    { 
    Mymap c1; 
 
    std::cout << "max_size() == " << c1.max_size() << std::endl; 
 
    return (0); 
    }
