ect the correct answerWhich fundamental operation is commonly used to exchange the values of two variables without using a temporary variable?OptionsAdditionMultiplicationSubtractionBitwise XOR
Solution
The correct answer is Bitwise XOR. This operation is commonly used to exchange the values of two variables without using a temporary variable. Here's how it works:
Let's say we have two variables, a and b. We want to swap their values.
- a = a XOR b
- b = a XOR b
- a = a XOR b
After these operations, the values of a and b will be swapped. This is because the XOR operation is both commutative and associative, meaning the order in which the operations are performed does not change the result.
