list::front (STL/CLR)

Accesses the first element.

    reference front();

The member function returns a reference to 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.

// cliext_list_front.cpp 
// compile with: /clr 
#include <cliext/list> 
 
int main() 
    { 
    cliext::list<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 first item 
    System::Console::WriteLine("front() = {0}", c1.front()); 
 
// alter first item and reinspect 
    c1.front() = L'x'; 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
    return (0); 
    }
