Noncompliant Code Example (right shift)

Wiki MarkupThe right-shift operation may be implemented as either an arithmetic (signed) shift or a logical (unsigned) shift. If {{E1}} in the expression {{E1 >> E2}} has a signed type and a negative value, the resulting value is implementation defined. Also, be careful to avoid [undefined behavior|BB. Definitions#undefined behavior] while performing a bitwise shift (see [INT34-C. Do not shift a negative number of bits or more bits than exist in the operand]).

 This noncompliant code example can result in an error condition on [implementations|BB. Definitions#implementation] in which an arithmetic shift is performed and the sign bit can beis propagated as the number is shifted \[[Dowd 06|AA. C References#Dowd 06]\].
