c++ - reversing a vector and printing it -

how reverse vector? i've read lot of online post can't find 1 using namespace std. need use reverse() , vect.reverse(); here code:

#include <iostream>  #include <vector> #include <iomanip>  using namespace std; int main() {    cout << "kaitlin stevers" << endl;    cout << "exercise 11 - vectors" << endl;    cout << "november 12, 2016" <<endl;    cout << endl;    cout << endl;    int size;    cout << " how many numbers vector hold? " << endl;    cin >> size;    vector<int> numbers;    int bnumbers;     (int count = 0; count < size; count++)    {        cout << "enter number: " << endl;        cin >> bnumbers;        numbers.push_back(bnumbers); // adds element numbers     }     //display numbers stored in order     cout << "the numbers in order are: " << endl;     for(int bcount = 0; bcount < size; bcount++)     {         cout << numbers[bcount] << " ";     }     cout << endl;     //display numbers stored reversed     reverse(numbers.begin(), numbers.end());    return 0; } 

you need include <algorithm> have access std::reverse.
last line in code work is, if include header.
