WebApr 4, 2024 · The following code illustrates simple program to count set bits in a randomly generated 64 K integer array. The idea is to generate a look up for first 256 numbers (one byte), and break every element of array at byte boundary. A meta program using C/C++ preprocessor generates the look up table for counting set bits in a byte. WebLossless bit compression. Computers represent all data in binary, so all types of files, from text to images to videos, are ultimately sequences of bits. Regardless of whether the bits represent a document or a GIF, computers can use a bit compression technique called Huffman coding.
