Question
What is the purpose of the expression x ^ y in C, where ^ is the bitwise XOR operator?
Solution
The expression 'x ^ y' in C is used to perform a bitwise XOR operation on the binary representations of the integers x and y. Here's how it works:
- Convert x and y to their binary representations.
- Align the binary representations of x and y.
- Perform the XOR operation on each pair of corresponding bits. The XOR operation returns 1 if the two bits are different, and 0 if they are the same.
- The result of 'x ^ y' is the integer represented by the binary result of the XOR operation.
This operation is often used in algorithms and data structures for tasks such as toggling bits, swapping values without a temporary variable, and finding missing numbers in arrays.
