[Solved] How can I make my program faster? [closed]

Question

If you look here: How are arrays passed?

Arrays are passed as pointers already, and your implementation of std::swap (which you called “exchange”) is already passing by reference. So that is not an issue in your case. Has your professor complained about your program execution speed?
