Important Operations

Number System Conversion

42₁₀ = 101010₂ = 2A₁₆
Base conversion between systems

Bit Shifting

n << k = n × 2^k
Fast multiplication/division

AND Operation (&)

1010 & 1100 = 1000
Bit masking and filtering

OR Operation (|)

1010 | 0101 = 1111
Set bits and combine

Tip: Bitwise operations are fundamental for low-level programming and performance optimization in software development.
