queue::difference_type (STL/CLR)
The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.
The latest version of this topic can be found at queue::difference_type (STL/CLR).
The types of a signed distance between two elements.
Syntax
typedef int difference_type;
Remarks
The type describes a possibly negative element count.
Example
// cliext_queue_difference_type.cpp
// compile with: /clr
#include <cliext/queue>
typedef cliext::queue<wchar_t> Myqueue;
int main()
{
Myqueue c1;
c1.push(L'a');
c1.push(L'b');
c1.push(L'c');
// display initial contents " a b c"
for each (wchar_t elem in c1.get_container())
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
// compute negative difference
Myqueue::difference_type diff = c1.size();
c1.push(L'd');
c1.push(L'e');
diff -= c1.size();
System::Console::WriteLine("pushing 2 = {0}", diff);
// compute positive difference
diff = c1.size();
c1.pop();
c1.pop();
c1.pop();
diff -= c1.size();
System::Console::WriteLine("popping 3 = {0}", diff);
return (0);
}
a b c
pushing 2 = -2
popping 3 = 3
