Another way to look at it is: 17 is 10001 in binary (base 2), so you need a shift operation for each of the bits set in the multiplier (i.e. bits 4 and 0, as above). WebApplying a single left bitshift gets us: 1101100 The leftmost zero was shifted out of the byte, and a new zero was appended to the right end of the byte. The bits don't rollover; they are discarded. That means if you left shift 1101100 and then right shift it, …

WebApr 10, 2024 · Bitwise Operators in C/C++. In C, the following 6 operators are bitwise operators (also known as bit operators as they work at the bit-level). They are used to perform bitwise operations in C. The & (bitwise AND) in C or C++ takes two numbers as operands and does AND on every bit of two numbers. The result of AND is 1 only if both … WebModular Math and the Shift Cipher. The Caesar Cipher is a type of shift cipher.
