What are some examples of bit manipulation in C++?

Bit manipulation in C++ involves using bitwise operators to perform operations on binary digits. Examples include setting, clearing, and toggling bits.

Can you show me how to set a specific bit in a number?

Sure! To set the nth bit of a number, you can use the bitwise OR operator. For example, to set the 3rd bit of a number x, you can do: x |= (1 << 3);

What about clearing a bit?

To clear the nth bit, you can use the bitwise AND operator with a negated bitmask. For example: x &= ~(1 << n); will clear the nth bit.

Are there performance benefits to using bit manipulation?

Yes, bit manipulation can lead to performance improvements, especially in scenarios involving large datasets or low-level programming, as it allows for faster operations compared to arithmetic.
