Bitwise operation in c++
WebMar 4, 2024 · Bitwise operators are special operator set provided by ‘C.’. They are used in bit level programming. These operators are used to manipulate bits of an integer expression. Logical, shift and complement are three types of bitwise operators. Bitwise complement operator is used to reverse the bits of an expression. WebC++ supports different types of bitwise operators that can perform operations on integers at bit-level. Supported types of bitwise operators include: & Bitwise AND. Bitwise OR. << Bitwise Left Shift. >> Bitwise Right Shift. ~ Bitwise Complement. ^ Bitwise XOR.
