title: Why use escape characters in C language
body: <p>Why use escape characters when writing a C program?</p>
  <p>I have been looking at this example program using the \a escape character which is shown in the bottom of the question.</p>
  <p>What is the purpose of this as on the console the print out is the same without the \a escape characters?</p>
  <pre><code>#include &lt;stdio.h&gt;
  int main(void)
  {
      printf(&quot;My mobile number &quot;
            &quot;is 7\a8\a7\a3\a9\a2\a3\a4\a0\a8\a&quot;);
      return (0);
  }
  </code></pre>
