title: Explicit type conversion in c language
body: <p>if my c code is</p>
  
  <pre><code>#include&lt;stdio.h&gt;
  int main()
  {
      int c;
      while((c=getchar())!=EOF)
      {
         putchar(c);
      }
  getch();
  return 0;
  }
  </code></pre>
  
  <p>I want to know whether <strong>int c</strong> woud be converted into <strong>char</strong> , or the input character would be converted into <strong>int</strong> and then be stored in c.   </p>
