title: how many spaces are considered in \t
body: <p>why the  number of space is different in case 3
  how the result is getting effected by \t character.</p>
  
  <p>(-) refers space by (\t)</p>
  
  <pre><code>case 1
   void main()
      {
          int a,b;
          printf("%d",printf("hello%d\t",scanf("%d%d",&amp;a,&amp;b)));
      }
  </code></pre>
  
  <p>here the output is>hello2-7</p>
  
  <pre><code>case 2
   void main()
      {
          int a,b;
          printf("%d",printf("hello\t%d",scanf("%d%d",&amp;a,&amp;b)));
      }
  </code></pre>
  
  <p>here the output is>hello-27</p>
  
  <pre><code>case 3
   void main()
      {
          int a,b;
          printf("%d",printf("\thello%d",scanf("%d%d",&amp;a,&amp;b)));
      }
  </code></pre>
  
  <p>here the output is>--------hello27
  Why in the 3rd case there are 8 spaces.</p>
