title: Quick way to fill vector, map, and set, using stl functions
body: <p>I want to fill these containers pretty quickly with some data for testing. What are the best and quick ways to do that? It shouldn't be too convoluted, and thus and inhumanly short,  but also NOT to verbose</p>
  
  <p><strong>Edit</strong></p>
  
  <p>Guys I thought you can do something with memset knowning that vector has an underlining array?
  Also, what about map?</p>
