title: to check the end of arrays
body: <pre><code>main()
  {
      char buff[10];
  
      int a;
  
      for(int i=0; i&lt;10;i++)
  
      {
  
          cin &gt;&gt; buff[i];
  
          a=sizeof(buff[i]);
  
          if(a==10)
  
              cout &lt;&lt; "full";
  
      }
  
      for(int i=0; i&lt;10;i++)
  
          cout &lt;&lt; buff[i]&lt;&lt;"\n";
  
  }
  </code></pre>
  
  <p>why des the control never comes to  cout &lt;&lt; "full"; i am new to coding...when i do dry run it works fine </p>
