Unlock the Power of Bitwise Operations in C#
The Hidden World of Binary
Bitwise operators are the unsung heroes of programming, allowing you to manipulate binary data at its core. While they may not be commonly used in everyday coding, understanding bitwise operations can elevate your skills and open doors to new possibilities.
Bitwise OR: The Union of Bits
The bitwise OR operator (|) performs a union of bits, resulting in 1 if either of the corresponding bits is 1. This operation is equivalent to a logical OR operation when working with boolean values. Let’s see it in action:
Example 1: Bitwise OR
When we run the program, the output will be: 15
Bitwise AND: The Intersection of Bits
The bitwise AND operator (&) finds the intersection of bits, resulting in 1 only if both corresponding bits are 1. This operation is equivalent to a logical AND operation when working with boolean values. Let’s see it in action:
Example 2: Bitwise AND
When we run the program, the output will be: 10
Bitwise XOR: The Magic of Exclusive OR
The bitwise XOR operator (^) performs an exclusive OR operation, resulting in 1 if the corresponding bits are different. This operation is equivalent to a logical XOR operation when working with boolean values. Let’s see it in action:
Example 3: Bitwise XOR
When we run the program, the output will be: 5
Bitwise Complement: Flipping the Bits
The bitwise complement operator (~) inverts each bit, changing 1 to 0 and 0 to 1. However, beware of the 2’s complement representation of negative numbers, which can lead to unexpected results. Let’s see it in action:
Example 4: Bitwise Complement
When we run the program, the output will be: -27 (but why?)
The Secret to Understanding 2’s Complement
In computer representation, negative numbers are stored in 2’s complement form. To find the 2’s complement of a number, simply invert the bits and add 1. Overflow values are ignored, leading to the unexpected result in our previous example.
Bitwise Left Shift: Shifting to the Left
The bitwise left shift operator (<<) shifts a number to the left by a specified number of bits, effectively multiplying it by 2 raised to the power of the shift value. Let’s see it in action:
Example 5: Bitwise Left Shift
When we run the program, the output will be: 168
Bitwise Right Shift: Shifting to the Right
The bitwise right shift operator (>>) shifts a number to the right by a specified number of bits, effectively dividing it by 2 raised to the power of the shift value. Let’s see it in action:
Example 6: Bitwise Right Shift
When we run the program, the output will be: 10
