Note Microsoft Visual C++ .NET 2002 and Microsoft Visual C++ .NET 2003 support both the managed code model that is provided by the Microsoft .NET Framework and the unmanaged native Microsoft Windows code model.

SUMMARY
The sample code below illustrates how to use the list::list STL functions in Visual C++.

<div class="moreinformation_section">

Required Header
Prototype explicit list(const A& al = A); explicit list(size_type n, const T& v = T, const A& al = A); list(const list& x); list(const_iterator first, const_iterator last, const A& al = A); NOTE: The class/parameter names in the prototype may not match the version in the header file. Some have been modified to improve readability.

Description
The first constructor specifies an empty initial controlled sequence. The second constructor specifies a repetition of n elements of value x. The third constructor specifies a copy of the sequence controlled by x. The last constructor specifies the sequence [first, last). All constructors store the allocator object al, or for the copy constructor, x.get_allocator, in allocator and initialize the controlled sequence.

typedef list<string, allocator > LISTSTR;

// Try each of the four constructors void main {   LISTSTR::iterator i;    LISTSTR test;                   // default constructor test.insert(test.end, "one"); test.insert(test.end, "two"); LISTSTR test2(test);           // construct from another list LISTSTR test3(3, "three");     // add several <T>'s    LISTSTR test4(++test3.begin,  // add part of another list             test3.end); // Print them all out // one two for (i = test.begin; i != test.end; ++i) cout << *i << " "; cout << endl; // one two for (i = test2.begin; i != test2.end; ++i) cout << *i << " "; cout << endl; // three three three for (i = test3.begin; i != test3.end; ++i) cout << *i << " "; cout << endl; // three three for (i = test4.begin; i != test4.end; ++i) cout << *i << " "; cout << endl; } Program Output is: <pre class="fixed_text">one two one two three three three three three
