Initializing a Vector with the Contents of an Array

You can initialize a vector with the contents of a built-in array like this:
#include <iostream>
using namespace std;

int main()
  int arr[3];
  arr[0] = 4; arr[1] = 8;  arr[2] = 16;
  vector <int> vi ( &arr[0],     // first argument is the address of  the array's beginning
                             &arr[3] );    // second argument must point one element past the array's end! 

  cout<< vi[0] << '\t' << vi[1] << '\t' << vi[2] <<endl;  // output: 4  8  16
