title: How to initialize pair<vector<pair<bool,int>>,vector<pair<bool,int>>> in C++11
body: <p>I'd like to initialize:</p>
  
  <pre><code>pair&lt;vector&lt;pair&lt;bool,int&gt;&gt;,vector&lt;pair&lt;bool,int&gt;&gt;&gt; pvp;
  </code></pre>
  
  <p>so that for all i:</p>
  
  <pre><code>pvp.first[i].first = true;
  </code></pre>
  
  <p>and    </p>
  
  <pre><code>pvp.second[i].first = false;
  </code></pre>
  
  <p>I know that you could do this with a loop but isn't there any faster way like an <a href="https://stackoverflow.com/questions/13110130/initialize-a-vector-to-zeros-c-c11">initialization for a vector</a>?</p>
