==Combine insert and begin to add element to the start of a list==

<source lang="cpp">#include <iostream>
using std::cout;
using std::endl;
#include <list> // list class-template definition
#include <algorithm> // copy algorithm
#include <iterator> // ostream_iterator
int main()
{
int array[ 4 ] = { 2, 6, 4, 8 };
std::list< int > values; // create list of ints
std::list< int > otherValues; // create list of ints
std::ostream_iterator< int > output( cout, " " );
// insert items in values
values.push_front( 1 );

cout << endl;
return 0;
}</source>
<pre class=codeResult>values contains: 3 1 4 2
values contains: 2 6 4 8 3 1 4 2</pre>

==Combine insert and end to add elements to the end of a list==

<source lang="cpp">#include <iostream>
#include <cassert>
#include <algorithm>
#include <string>
#include <list>
#include <iostream>
using namespace std;

}</source>
<pre class=codeResult>AAA
BBBB
CCCCC</pre>

==Insert 3 fours==

<source lang="cpp">#include <list>
#include <iostream>

==Insert an array in there==

<source lang="cpp">#include <list>

==Insert another list==

<source lang="cpp">#include <list>

==Insert elements of array into a list==

<source lang="cpp">#include <iostream>
using std::cout;
using std::endl;
#include <list> // list class-template definition
#include <algorithm> // copy algorithm
#include <iterator> // ostream_iterator
int main()

std::list< int > values; // create list of ints

// insert items in values
values.push_front( 1 );
values.push_front( 3 );
values.push_back( 4 );

cout << "values contains: ";
std::copy( values.begin(), values.end(), output );
values.insert( values.begin(), array, array + 4 );
cout << "\n\nvalues contains: ";
std::copy( values.begin(), values.end(), output );
cout << endl;
return 0;
}</source>
<pre class=codeResult>values contains: 3 1 4 2
values contains: 2 6 4 8 3 1 4 2</pre>

==Inserting elements from another list at the beginning==

<source lang="cpp">#include <list>
#include <iostream>
using namespace std;
void PrintListContents (const list <int>& listInput);
int main ()
{
list <int> list1;
list1.insert (list1.begin (), 4);
list1.insert (list1.begin (), 3);

// Inserting elements from another list at the beginning...

{
std::list <int>::const_iterator i;
for ( i = listInput.begin (); i != listInput.end (); ++ i )
cout << *i << endl;
}</source>

==Inserting elements from another list at the end==

<source lang="cpp">#include <list>
#include <iostream>
using namespace std;
void PrintListContents (const list <int>& listInput);
int main ()
{
list <int> list1;
list1.insert (list1.begin (), 4);

{
std::list <int>::const_iterator i;
for ( i = listInput.begin (); i != listInput.end (); ++ i )
cout << *i << " ";
}</source>

==Inserting Elements in the List Using push_back==

<source lang="cpp">#include <list>
#include <iostream>
int main ()
{
std::list <int> listIntegers;
listIntegers.push_back (1);
listIntegers.push_back (2);
listIntegers.push_back (-1);

std::list <int> ::iterator i;
for ( i = listIntegers.begin (); i != listIntegers.end (); ++ i )
std::cout << *i << std::endl;
return 0;
}</source>

==Inserting Elements in the List Using push_front==

<source lang="cpp">#include <list>
#include <iostream>
int main ()
{
std::list <int> listIntegers;
listIntegers.push_front (10);
listIntegers.push_front (2001);
listIntegers.push_front (-1);
listIntegers.push_front (9999);
std::list <int> ::iterator i;
for ( i = listIntegers.begin (); i != listIntegers.end (); ++ i )
std::cout << *i << std::endl;
return 0;
}</source>

==Insert one at a time==

<source lang="cpp">#include <list>
#include <iostream>
using namespace std;
typedef list<int> LISTINT;
int main(void)
{
int rgTest1[] = {5,6,7};
int rgTest2[] = {10,11,12};
LISTINT listInt;
LISTINT listAnother;
LISTINT::iterator i;
// Insert one at a time
listInt.insert (listInt.begin(), 2);
listInt.insert (listInt.begin(), 1);
listInt.insert (listInt.end(), 3);
for (i = listInt.begin(); i != listInt.end(); ++i)
cout << *i << endl;
}</source>
