Speaking in C language a bit operation entry level (detailed illustration)

1. All the numbers in the program are stored in binary form in the computer's memory . Bitwise arithmetic is the direct operation of an integer in memory bits.

2. And operation: only the first and the two operands are 1 and the result is 1.

3. Or operation: 1 bits are 1, and the result is 1.

4. XOR: Not the same is 1.

5. Take the inverse operation: Change 1 to 0 and 0 to 1.

6. Shift operation: Shift left is multiply by 2, and right moves except 2. Discard if the boundary is exceeded.
