title: How to put a new line inside a string in C++?
body: <p>I was thinking if it is possible to make a string in C++ which contains data in it like, I don't want to make a string of strings or an array of strings.</p>
  
  <p>Suppose I have a string <code>mv</code>:</p>
  
  <pre><code>mv =  
  "hello         
   new                   
   world "
  </code></pre>
  
  <p>"hello", "new" and "world" are in different lines. Now if we print <code>mv</code>, then "hello", "new" and "world" should come on different lines.</p>
  
  <p>I was also thinking with respect to competitive programming. If I concatenate all the answers of queries in a single string and then output the answer, or <code>cout</code> all the queries one by one, will there be a time difference in both the outputs?</p>
