   v[2] = 0.0;

   // make the vector as large as possible without reallocating
   v.resize( v.capacity(), 2.78 );

   // find the smallest number
   vector<double>::iterator before_itr = min_element( v.begin(), v.end() );

   // append one more element. This causes reallocation
   v.push_back( 2.78 );
