What are some examples of bitwise operations in C?

Can you explain what bitwise operations are in C?

Bitwise operations in C are operations that directly manipulate bits of binary numbers. They include AND, OR, XOR, NOT, and bit shifts.

Can you give me examples of each bitwise operation?

Sure! Here are examples:

1. AND: a & b
2. OR: a | b
3. XOR: a ^ b
4. NOT: ~a
5. Left Shift: a << 1
6. Right Shift: a >> 1.

What do these operations do to the binary representation?

Each operation affects the bits:

• AND sets bits to 1 if both bits are 1.
• OR sets bits to 1 if at least one bit is 1.
• XOR sets bits to 1 if the bits are different.
• NOT inverts the bits.
• Left Shift moves bits left, filling with 0s.
• Right Shift moves bits right, also filling with 0s.

Can you show me a code snippet using these operations?

Certainly! Here's a simple example:

#include <stdio.h>

int main() {
    int a = 5; // 0101 in binary
    int b = 3; // 0011 in binary
    printf("AND: %d\n", a & b); // Output: 1
    printf("OR: %d\n", a | b); // Output: 7
    printf("XOR: %d\n", a ^ b); // Output: 6
    printf("NOT: %d\n", ~a); // Output: -6
    printf("Left Shift: %d\n", a << 1); // Output: 10
    printf("Right Shift: %d\n", a >> 1); // Output: 2
    return 0;
}
