A Guide on How to Swap Two Variables Across Different Programming Languages

Swapping two variables is a common task in programming that can be accomplished using various techniques. This guide explores the different methods of swapping variables, both with and without using a third variable, and demonstrates how to perform these swaps in Python and C++. By the end, you will have a comprehensive understanding of how to effectively swap two variables in different programming contexts.

Swapping Variables using a Third Variable

The most straightforward and universally understood method for swapping two variables involves using a temporary third variable. Here's how you can do it:
