title: Storing and printing 10+ digit integer in c++
body: <p>I'm using cout to print digits to the console. I am also storing values of up to 13+billion as a digit and doing computations on it. What data type should I use?</p>
  
  <p>When I do the following:</p>
  
  <pre><code>int a = 6800000000;
  cout &lt;&lt; a;
  </code></pre>
  
  <p>It prints -1789934592.</p>
  
  <p>thanks.</p>
