Improve Your Programming with Asserts
by Bruce D. Rosenblum 

Example 1:
(a)
h = GlobalAlloc(size_t, flags);
ASSERT(h != NULL, "Allocation failed");

(b) 
m_pBtn = new CButton ();
ASSERT(m_pBtn != NULL, "Button not instantiated");

Example 2:
m_bmpSplash.LoadDIBitmap ( IDB_SPLASH );
ASSERT( m_bmpSplash != NULL, "Bitmap not loaded");

Example 3:
(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 4:
(a)
VERIFY((z = x * y) < kMaxValue);

(b)
z = x * y;
ASSERT( z < kMaxValue, "z exceeds valid limit");
