title: Passing a array of std::string by reference
body: <p>I'ld like to create a function that passes not a std::string by reference to be modified,</p>
  
  <pre><code>void changeStr(std::string &amp;str)
  {
      str = "Hello World!";
  }
  </code></pre>
  
  <p>, but rather an entire, fixed-sized array of std::strings (the function will do exactly the same: attribute some specific strings to each space in the array). But I don't know which is the appropriate syntax... </p>
