hash_set::rbegin (STL/CLR)

 

The latest version of this topic can be found at hash_set::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_hash_set_rbegin.cpp   
// compile with: /clr   
#include <cliext/hash_set>   
  
typedef cliext::hash_set<wchar_t> Myhash_set;   
int main()   
    {   
    Myhash_set 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();   
  
// inspect first two items in reversed sequence   
    Myhash_set::reverse_iterator rit = c1.rbegin();   
    System::Console::WriteLine("*rbegin() = {0}", *rit);   
    System::Console::WriteLine("*++rbegin() = {0}", *++rit);   
    return (0);   
    }  
  

 a b c  
*rbegin
() = c  
*++rbegin
() = b
