title: the size of two dimensional array in C
body: <p>I have the following two dimensional array:</p>
  
  <pre><code>#define ROW 100
  #define LINE 50
  
  int a[ROW][LINE];
  </code></pre>
  
  <p>but how to get the sizeof array for the last 45 rows, for example <code>a[55][0]</code> to <code>a[99][99]</code>?</p>
  
  <p>can we do something like <code>sizeof(&amp;a[55])</code>?</p>
