Yes, as I posted yesterday: Subject: Re: [Cs323] flushBits > Message Posted By: Unknown > > When do you need to call flushBits()? Suppose that stdin contains one character, and that encode is running in Stage 3 and has assigned a code to the empty string. Then encode will call putBits() to write one 9-bit code to stdout. putBits() can only output the high-order 8 bits of this code and thus must save the low-order bit for the next call. But unless encode calls flushBits() (or does something equivalent), there will not be a next call and the low-order bit will never be output. --Stan-PREV INDEX NEXT
