#include <vector>

#include <iostream.h>

int main ()

{

// Initialize a vector with an array of integers.

int arr[10] = { 1,2,3,4,5,6,7,8,9,10 };

vector<int> v(arr+0, arr+10);

// Print out elements in original (sorted) order.

cout << "Elements before reverse: " << endl << " ";

copy(v.begin(), v.end(), ostream_iterator<int>(cout," "));

cout << endl << endl;

// Reverse the ordering.

reverse(v.begin(), v.end());

// Print out the reversed elements.

cout << "Elements after reverse: " << endl << " ";

copy(v.begin(), v.end(), ostream_iterator<int>(cout," "));

cout << endl << endl;

cout << "A reverse_copy to cout: " << endl << " ";

reverse_copy(v.begin(), v.end(), ostream_iterator<int>(cout, "

"));

cout << endl;

return 0;

}

Output :

Elements before reverse:

1 2 3 4 5 6 7 8 9 10

Elements after reverse:

10 9 8 7 6 5 4 3 2 1

A reverse_copy to cout:

1 2 3 4 5 6 7 8 9 10

Warning

If your compiler does not support default template parameters, then you need to always supply the Allocator template

argument. For instance, you will need to write :

vector<int, allocator>

instead of :

vector<int>
