Swap Two Variables in Programming: A Simple Explanation

These three lines of code are used to swap the values of two variables, 'x' and 'y'.

The first line assigns the value of 'x' to a temporary variable 't'. The second line assigns the value of 'y' to 'x', effectively swapping the value of 'x' with 'y'. The third line assigns the value of 't' (which is the original value of 'x') to 'y', completing the swap of values between 'x' and 'y'.

After these three lines of code are executed, the values of 'x' and 'y' will have been swapped.
