I want to make a swap function i just dont know how.

Question

Anyone got an idea of an algorithim to make swap function.

Answer 1

https://www.programiz.com/cpp-programming/examples/swapping

See this 👆🏻

The function std::swap() is a built-in function in the C++ Standard Template Library (STL) which swaps the value of two variables. Parameters: The function accepts two mandatory parameters a and b which are to be swapped. The parameters can be of any data type.

Answer 2

Think of it as switching liquid between 2 vessels.{v1 and v2}
First you would need an extra third vessel{v3} to empty one{say v1} and then pour liquid from {v2} to {v1} then from {v3} to {v2}.

Just apply this in programming where vessels are nothing but variables.

P.S. there are other ways also to swap them even without the third variable. I leave that for you to explore.
