title: After making a choice , how can i delete the previous words ? C++
body: <p>Okay , I'm writing my first project for my college , 
  I need to make a trick in my code 
  which i believe it's possible to do ,
  First of all here's my code : </p>
  
  <pre><code>cout &lt;&lt; "1 - Enter the program\n" 
       &lt;&lt; "2 - About the program\n"
       &lt;&lt; "3 - EXIT" &lt;&lt; endl; //calls exit function .
  cin &gt;&gt; choice;
  </code></pre>
  
  <p>After this very first line of code execution , the compiler calls a function which also has a bunch of couts and cins , </p>

  <p>What exactly i need to make is when i choose 1 or 2 
  all the previous words should be cleared except the program title .</p>
