Though we are calling it as a bitwise operators, it always operate on one or more bytes i.e, it will consider the whole representation of the number when applying bitwise operators. By using some techniques, we can manipulate a single bit on the whole representation of the number as we wi...
Bitwise Exclusive-Or (XOR) 1 2 3 4 01110010 ^ 10101010 --- 11011000 solution 1 2 3 4 voidflip_use_state(intcar_num) { in_use = in_use ^ 1<<car_num; } When should you use bitwise operators? Summary Works on bits for left argument, takes an integer as a second argument 1...
Demystifying bitwise operations, a gentle C tutorial Understanding the Power of Bitwise Operators. No math needed Memory Allocation (an interactive article) Why does 0.1 + 0.2 = 0.30000000000000004?, Julia Evans (about floating point) Putting the "You" in CPU Machine learning/AI Transformers from ...
It consists of a large number of bitwise, logical and arithmetic operators: +, +=, ++, &, ||, etc. C has a fixed number of keywords (i.e. small set), so it also provides us a free hand to use multiple terms throughout the code. It also includes a full set of control flow ...
// only bitwise operators used. // here count works as my flag if we find a 1 in value, we shift count // to the right. I assume that 2^0 = 1 is a proper power of 2. bool isPowerOfTwo(int value) { int count = 1; ...
Code analysis check for bitwise shift operators. It also provides support for__attribute__(unused)and__builtin_unreachable. C++14 digit separatorCopy heading link The last but not the least, is C++14 digit separator support. Not that much to say here except that it now works, but it does...

Expert C programming is a book written by Peter Van Der Linden is a second book which offers many advanced tips and tricks. This book helps C programmer to scan the sections that are relevant to their immediate needs. The book explains various coding techniques which is used by the best C...
All these tricks are extremely confusing and should not be used in code intended to be readable. There is no way to prevent a backslash at the end of a line from being interpreted as a backslash-newline. This cannot affect any correct program, however. 1.3 Tokenization After the textual ...
As far as I am aware, C++ was the first widely accepted language to use generics, and was definitely the first to make it a standard part of the programmer’s arsenal (provided that various C void* tricks aren’t really generic programming). ...
