C++ Bitwise Operations Fundamentals: Bitwise Extraction and Flag Setting
In actual C++ development, bitwise operations are a common technique, especially when dealing with system states, flags, or control bits. Bitwise operations can provide very efficient solutions. This article will illustrate how to use bitwise operations to retrieve and set specific flags through an example.
Bitwise Operations Fundamentals In computers, data is stored in binary bits (0 and 1). Bitwise operations are operations performed on these binary bits. C++ provides several commonly used bitwise operators:
