How to Swap Two Numbers in C++ Using a Third Variable
Swap two numbers in C++ using a third variable — explained step by step with memory diagrams and a clear walkthrough of why the third variable is needed in the first place.
This video covers the classic C++ swap program using a temporary variable, why a direct two-line swap fails, the role of the temp variable, the correct order of assignment statements, and how the values move around in stack memory when the program runs. A great fundamentals exercise for anyone learning C++, variables, and assignment.
