Example

// cliext_collection_adapter_begin.cpp   
// compile with: /clr   
#include <cliext/adapter>   
#include <cliext/deque>   
  
typedef cliext::collection_adapter<   
    System::Collections::ICollection> Mycoll;   
int main()   
    {   
    cliext::deque<wchar_t> d1;   
    d1.push_back(L'a');   
    d1.push_back(L'b');   
    d1.push_back(L'c');   
    Mycoll c1(%d1);   
  
// 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   
    Mycoll::iterator it = c1.begin();   
    System::Console::WriteLine("*begin() = {0}", *it);   
    System::Console::WriteLine("*++begin() = {0}", *++it);   
    return (0);   
    }
