C++ Tutorial/vector/vector swap

#include <vector>
using namespace std;
int main(int argc, char** argv)
{
  vector<int> intVector(10, 0);
  intVector.assign(5, 100);
  vector<int> v1(10, 0);
  vector<int> v2(5, 100);
  v1.swap(v2);
  // v1 now has 5 elements with the value 100.
  // v2 now has 10 elements with the value 0
  return (0);
