Compiler Warning (level 1) C4333

'operator' : right shift by too large amount, data loss

A right shift operation was too large an amount. All significant bits are shifted out and the result will always be zero.

Example

The following sample generates C4333.

// C4333.cpp
// compile with: /c /W1
unsigned shift8 (unsigned char c) {
   return c >> 8;   // C4333

   // try the following line instead
   // return c >> 4;   // OK
}
