collection_adapter::difference_type (STL/CLR)

The types of a signed distance between two elements.

    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); 
    } 
 

a b c end()-begin() = 3
