title: Easy way to make vector triplet in CPP
body: <p>What would be an easy way to construct a vector triplet of ints in CPP?</p>
  
  <p>i.e instead of a pair of 2 ints , </p>
  
  <pre><code>std::vector&lt;std::pair&lt;int, int&gt; &gt; vec;
  </code></pre>
  
  <p>I want 3 int's tied together as one element of the vector.</p>
  
  <p>I realized one way would be to make 2 sub-nested pairs, but this method gets messy. I am not aware of all the details of CPP, therefore please recommend an easier way if available. Thank you.</p>
