Reverse all elements in a vector by using reverse

 
 


#include <iostream>
#include <vector>
#include <algorithm>
using namespace std;

int main()
{
  vector<int> v;
  unsigned int i;

  for(i=0; i<10; i++) v.push_back(i);

  cout << "Initial: ";
  for(i=0; i<v.size(); i++) cout << v[i] << " ";
  cout << endl;

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

  cout << "Reversed: ";
  for(i=0; i<v.size(); i++) cout << v[i] << " ";

  return 0;
}

/* 
Initial: 0 1 2 3 4 5 6 7 8 9
Reversed: 9 8 7 6 5 4 3 2 1 0
