multiset::difference_type (STL/CLR)

The types of a signed distance between two elements.

    typedef int difference_type;

Remarks

The type describes a possibly negative element count.

Example

// cliext_multiset_difference_type.cpp 
// compile with: /clr 
#include <cliext/set> 
 
typedef cliext::multiset<wchar_t> Mymultiset; 
int main() 
    { 
    Mymultiset c1; 
    c1.insert(L'a'); 
    c1.insert(L'b'); 
    c1.insert(L'c'); 
 
// display initial contents " a b c" 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
// compute positive difference 
    Mymultiset::difference_type diff = 0; 
    for (Mymultiset::iterator it = c1.begin(); it != c1.end(); ++it) 
        ++diff; 
    System::Console::WriteLine("end()-begin() = {0}", diff); 
 
// compute negative difference 
    diff = 0; 
    for (Mymultiset::iterator it = c1.end(); it != c1.begin(); --it) 
        --diff; 
    System::Console::WriteLine("begin()-end() = {0}", diff); 
    return (0); 
    } 
 

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