deque::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_deque_difference_type.cpp
// compile with: /clr
#include <cliext/deque>
int main()
{
cliext::deque<wchar_t> c1;
c1.push_back(L'a');
c1.push_back(L'b');
c1.push_back(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
cliext::deque<wchar_t>::difference_type diff = 0;
for (cliext::deque<wchar_t>::iterator it = c1.begin();
it != c1.end(); ++it) ++diff;
System::Console::WriteLine("end()-begin() = {0}", diff);
// compute negative difference
diff = 0;
for (cliext::deque<wchar_t>::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
