Bitwise Operators

Description

Operators that work on bits. `&` (AND), `|` (OR), `^` (XOR), `<<` (Left Shift), `>>` (Right Shift), `&^` (Bit Clear).

Pros & Cons

✅ Pros

  • Low-level manipulation.
  • Performance optimizations.

❌ Cons

  • Complexity: Harder to read.

When to Use

Cryptography, flags, and hardware protocols.

Example

Bit manipulation.

var x uint8 = 0b00001100 // 12
var y uint8 = 0b00001010 // 10

fmt.Printf("%08b\n", x & y) // AND
fmt.Printf("%08b\n", x | y) // OR
fmt.Printf("%08b\n", x ^ y) // XOR

Best Practices

Go has a special `&^` AND NOT operator useful for clearing bits.
