WebMar 7, 2024 · Formally, the C++ standard makes no guarantee on the accuracy of floating-point operations. Unary arithmetic operators The unary arithmetic operator expressions have the form 1) unary plus (promotion). For the built-in operator, expression must have arithmetic, unscoped enumeration, or pointer type. WebBitwise operators are used to change individual bits in an operand. In C++, bitwise operators perform operations on integer data at the individual bit-level. These operations include testing, setting, or shifting the actual bits. It can be used as a boolean variable that can hold one of two values: True or False.

WebTo perform bit-level operations in C programming, bitwise operators are used. Bitwise AND Operator & The output of bitwise AND is 1 if the corresponding bits of two operands is 1. If either bit of an operand is 0, the result of corresponding bit is evaluated to 0. In C Programming, the bitwise AND operator is denoted by &. Webint i = 512; i & 0xFF; // this gives me the first byte That must mean i & 0xFF gives me the first byte that is stored in memory. In other words, i & 0xFF is the first of the four bytes i consists of stored at the lowest memory address. Next, I think that i << 8 & 0xFF will then shift everything left by 8 bits and giving me the second byte.
