title: Huge array on C++
body: <p>I solve some problem using C++. I have a huge array of double-s. It is used during all the process of solution, the program adresses to its different parts both reading them and changing ones.</p>
  
  <p>What type of container is the most proper for this situation? It must get access to the elemetns quilckly and store the data properly.</p>
  
  <p>Is it good idea to use
  <code>std::vector&lt;double&gt;</code>?</p>
