hash_multiset::difference_type (STL/CLR)
Die Typen eines Abstands mit Vorzeichen zwischen zwei Elementen.
typedef int difference_type;
Hinweise
Der Typ beschreibt eine Anzahl des möglicherweise negativen Elements.
Beispiel
// cliext_hash_multiset_difference_type.cpp
// compile with: /clr
#include <cliext/hash_set>
typedef cliext::hash_multiset<wchar_t> Myhash_multiset;
int main()
{
Myhash_multiset 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
Myhash_multiset::difference_type diff = 0;
for (Myhash_multiset::iterator it = c1.begin(); it != c1.end(); ++it)
++diff;
System::Console::WriteLine("end()-begin() = {0}", diff);
// compute negative difference
diff = 0;
for (Myhash_multiset::iterator it = c1.end(); it != c1.begin(); --it)
--diff;
System::Console::WriteLine("begin()-end() = {0}", diff);
return (0);
}
