The latest version of this topic can be found at collection_adapter::difference_type (STL/CLR).

The types of a signed distance between two elements.

Syntax

typedef int difference_type;  

Remarks

The type describes a signed element count.

Example

// cliext_collection_adapter_difference_type.cpp   
// compile with: /clr   
#include <cliext/adapter>   
#include <cliext/deque>   
  
typedef cliext::collection_adapter<   
    System::Collections::ICollection> Mycoll;   
int main()   
    {   
    cliext::deque<wchar_t> d1;   
    d1.push_back(L'a');   
    d1.push_back(L'b');   
    d1.push_back(L'c');   
    Mycoll c1(%d1);   
  
// display initial contents " a b c"   
    for each (wchar_t elem in c1)   
        System::Console::Write(" {0}", elem);   
    System::Console::WriteLine();   
  
// compute positive difference   
    Mycoll::difference_type diff = 0;   
    Mycoll::iterator it = c1.begin();   
    for (; it != c1.end(); ++it)   
        ++diff;   
    System::Console::WriteLine("end()-begin() = {0}", diff);   
    return (0);   
    }
