Bitwise operations in C Bitwise operations in C In the C programming language, operations can be performed on a bit level using bitwise operators. Bitwise operations are contrasted by byte-level operations which characterize the bitwise operators' logical counterparts, the AND, OR and NOT operators. Instead of performing on individual bits, byte-level operators perform on strings of eight bits (known as bytes) at a time. The reason for this is that a byte is normally the smallest unit of addressable memory (i.e. data with a unique memory address.) This applies to bitwise operators as well, which means that even though they operate on only one
Lempel–Ziv–Markov chain algorithm just adds the distance to the front even if already present in the list and SHORTREP and LONGREP[0] don't alter the list. The length is encoded as follows:<br> As in LZ77, the length is not limited by the distance, because copying from the dictionary is defined as if the copy was performed byte by byte, keeping the distance constant. Distances are logically 32-bit and distance 0 points to the most recently added byte in the dictionary. The distance encoding starts with a 6-bit "distance slot", which determines how many further bits are needed. Distances are decoded as a binary concatenation
