deque::front (STL/CLR)

 

The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The latest version of this topic can be found at deque::front (STL/CLR).

Accesses the first element.

Syntax

reference front();  

Remarks

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.

Example

// cliext_deque_front.cpp   
// compile with: /clr   
#include <cliext/deque>   
  
int main()   
    {   
    cliext::deque<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);   
    }
