Improve Your Programming with Asserts

By Bruce D. Rosenblum

Dr. Dobb's Journal December 1997

(a)
if ( m_hinst == NULL )
  ASSERT( FALSE, "Null Handle");
(b)
ASSERT( m_hinst != NULL, "Null Handle");
(c)
switch ( i )
{
  case 1:
    DoSomething ();
    break;
  case 2:
    DoSomething2 ();
    break;
  default:
    ASSERT ( FALSE, "Unknown switch case" );
}

Example 3: Do not assert FALSE. Do not use (a), use (b) instead. If you have a switch statement that has no default case, it should be unconditionally asserted like (c).
