Web11. jul 2015. · C.) Let n > 2 be а positive integer. How many bit strings of length n are there with exactly two zeroes? Work: Part A is relatively simple. Since a bit consists of either the number 1 or 0, there are only two ways that the first slot can be filled or ${2^n}$ ways. Since there are eight bits, the answer would be ${2^8}$ or 256. Different CPUs support different integral data types. Typically, hardware will support both signed and unsigned types, but only a small, fixed set of widths. The table above lists integral type widths that are supported in hardware by common processors. High level programming languages provide more possibilities. It is common to have a 'double width' integral type that has twice as many bits as the biggest hardware-supported type. Many l…

Web15. sep 2006. · Your solution doesn't appear to cope with integers wider than 21 bits, for a start. Secondly, it doesn't cope with integers that are /fewer/ than 21 bits wide! Thirdly, it could conceivably be counting "padding bits", bits that do not contribute to the value of the integer. I'm not sure if it's undefined behaviour to left shift an unsigned int by Weblog 2 ( n!) = log 2 [ n ⋅ ( n − 1) ⋯ 1] = log 2 n + log 2 ( n − 1) + ⋯ + log 2 1. There are n terms, and most of the terms are close to log 2 n in magnitude. Therefore log 2 ( n!) = Θ ( n log n). (To prove this more formally, use Stirling's approximation.)

"WebNote: one of the popular non-C/C++ approaches on the PDP-10 was to pack 5 bytes (of 7-bits each) into each 36-bit word. However this won’t work in C or C++ since 5×7 is 35, meaning using char* s to walk through memory would “skip” a bit every fifth byte (and also because C++ requires bytes to have at least 8 bits).
