In this tutorial, we dive into one of the most common C programming interview questions: swapping two numbers without a third variable. We’ll explain the logic behind using simple math (addition and subtraction) and show you a secondary method using the bitwise XOR operator.

The logic behind a = a + b, b = a - b, and a = a - b.Alternative bitwise XOR approach for efficiency.
