Summary

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

More information

Required Header

   <list>
				
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.

Sample Code

#include <list>
#include <string>
#include <iostream>

#if _MSC_VER > 1020   // if VC++ version is > 4.2
   using namespace std;  // std c++ libs implemented in std
   #endif

typedef list<string, allocator<string> > 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:
one two
one two
three three three
three three
