WebSep 28, 2024 · The bitwise AND operator in C++ is a single ampersand, & , used between two other integer expressions. Bitwise AND operates on each bit position of the surrounding expressions independently, according to this rule: if both input bits are 1, the resulting output is 1, otherwise the output is 0. Another way of expressing this is: 1 0 & 0 == 0 WebBack to: C++ Tutorials For Beginners and Professionals Enum and Typedef in C++ with Examples: In this article, I am going to discuss Enum which is an enumerated data type, and Typedef in C++ with Examples.
