title: How can I return a string to the operating system in my C code?
body: <p>I am a C beginner and this is my C code:</p>
  
  <pre><code>#include &lt;stdio.h&gt;
  #include &lt;stdlib.h&gt;
  
  main()
  {
      printf("Hello, World!\n");
      return 'sss';
  }
  </code></pre>
  
  <p>That will show an error. So how can I return a string in C code?</p>
