Swap without using a third variable. (C++)

[Prime-5]

Check that your method has not already been implemented in https://github.com/Prime-5/Algorithms/tree/master/Swap-without-third-variable/

Have a look at the swap.md file in there if you are out of ideas.
Think outside the box. Make it interesting. Take out an idea hiding in plain sight.

Only one solution is allowed per person. Also, don't forget to number you solution file.

Carpe Diem!
