map::rbegin (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 map::rbegin (STL/CLR).
Designates the beginning of the reversed controlled sequence.
Syntax
reverse_iterator rbegin();
Remarks
The member function returns a reverse iterator that designates the last element of the controlled sequence, or just beyond the beginning of an empty sequence. Hence, it designates the beginning
of the reverse sequence. You use it to obtain an iterator that designates the current
beginning of the controlled sequence seen in reverse order, but its status can change if the length of the controlled sequence changes.
Example
// cliext_map_rbegin.cpp
// compile with: /clr
#include <cliext/map>
typedef cliext::map<wchar_t, int> Mymap;
int main()
{
Mymap c1;
c1.insert(Mymap::make_value(L'a', 1));
c1.insert(Mymap::make_value(L'b', 2));
c1.insert(Mymap::make_value(L'c', 3));
// display contents " [a 1] [b 2] [c 3]"
for each (Mymap::value_type elem in c1)
System::Console::Write(" [{0} {1}]", elem->first, elem->second);
System::Console::WriteLine();
// inspect first two items in reversed sequence
Mymap::reverse_iterator rit = c1.rbegin();
System::Console::WriteLine("*rbegin() = [{0} {1}]",
rit->first, rit->second);
++rit;
System::Console::WriteLine("*++rbegin() = [{0} {1}]",
rit->first, rit->second);
return (0);
}
[a 1] [b 2] [c 3]
*rbegin
() = [c 3]
*++rbegin
() = [b 2]
