AuctionEntry entry("painting", "2021-08-01 10:00:00", "2021-08-08 10:00:00", 100, 0);
entry.updateBid(150);
if (entry.auctionEnded()) { std::cout << "The auction has ended." << std::endl; } else { std::cout << "The auction is still ongoing." << std::endl; }This checks if the current time is past the end time of the auction and prints a message accordingly. Based on the naming convention and the fact that there are no external dependencies, it is likely that AuctionEntry is part of a custom package or library.
