title: How to operate on two vectors and save the result to another vector
body: <pre><code>vector&lt;int&gt; vecIntsA{1, 2, 3, 4};
  vector&lt;int&gt; vecIntsB{5, 6, 7, 8};
  vector&lt;int&gt; vecIntsC(vecIntsA.size(), 0);
  
  for(vector&lt;int&gt;::size_type i = 0; i &lt; vecIntsA.size(); ++i)
  {
      vecIntsC[i] = vecIntsA[i] + vecIntsB[i];
  }
  </code></pre>
  
  <p>Question> Is there a STL algorithm that can be used to make this calculation be done in one line?</p>
