Accesses the first element.

Syntax

property value_type front_item;

Remarks

The property accesses the first element of the controlled sequence, which must be non-empty. You use it to read or write the first element, when you know it exists.

Example

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