queue::back (STL/CLR)

Accesses the last element.

    reference back();

Remarks

The member function returns a reference to the last element of the controlled sequence, which must be non-empty. You use it to access the last element, when you know it exists.

Example

// cliext_queue_back.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(); 
 
// inspect last item 
    System::Console::WriteLine("back() = {0}", c1.back()); 
 
// alter last item and reinspect 
    c1.back() = L'x'; 
    for each (wchar_t elem in c1.get_container()) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
    return (0); 
    } 
 
 a b c
back() = c
 a b x
