vector::back (STL/CLR)

Accesses the last element.

Syntax

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_vector_back.cpp   
// compile with: /clr   
#include <cliext/vector>   

int main()   
    {   
    cliext::vector<wchar_t> c1;   
    c1.push_back(L'a');   
    c1.push_back(L'b');   
    c1.push_back(L'c');   

// display initial contents " a b c"   
    for each (wchar_t elem in c1)   
        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)   
        System::Console::Write(" {0}", elem);   
    System::Console::WriteLine();   
    return (0);   
    }  
 a b c  
back() = c  
 a b x
