hash_map::size_type (STL/CLR)

The type of a signed distance between two element.

    typedef int size_type;

Remarks

The type describes a non-negative element count.

Example

// cliext_hash_map_size_type.cpp 
// compile with: /clr 
#include <cliext/hash_map> 
 
typedef cliext::hash_map<wchar_t, int> Myhash_map; 
int main() 
    { 
    Myhash_map c1; 
    c1.insert(Myhash_map::make_value(L'a', 1)); 
    c1.insert(Myhash_map::make_value(L'b', 2)); 
    c1.insert(Myhash_map::make_value(L'c', 3)); 
 
// display contents " [a 1] [b 2] [c 3]" 
    for each (Myhash_map::value_type elem in c1) 
        System::Console::Write(" [{0} {1}]", elem->first, elem->second); 
    System::Console::WriteLine(); 
 
// compute positive difference 
    Myhash_map::size_type diff = 0; 
    for (Myhash_map::iterator it = c1.begin(); it != c1.end(); ++it) 
        ++diff; 
    System::Console::WriteLine("end()-begin() = {0}", diff); 
    return (0); 
    } 
 

 [a 1] [b 2] [c 3]
end()-begin() = 3
