title: if int A[5] is declared then only A is pointer to the A[0].which means A is just a pointer . then how come sizeof(A) gives answer as 20
body: <p>Suppose if <code>int A[5]</code> is declared  then variable <code>A</code> will be  pointer to the <code>A[0]</code>. Which means <code>A</code> is just a pointer and <code>A</code> stores the base address of array <code>A[5]</code> . Then how come <code>sizeof(A)</code> gives answer as 20</p>
