AuctionEntry entry("item1", "seller1", 100, 10); AuctionInfo info = BuildAuctionInfo(entry); // Access the auction information fields std::cout << "Item name: " << info.itemName << std::endl; std::cout << "Seller name: " << info.sellerName << std::endl; std::cout << "Current bid: " << info.currentBid << std::endl; std::cout << "Number of bids: " << info.numBids << std::endl;In this example, we create a new AuctionEntry object representing an item named "item1" being sold by a seller named "seller1", with an initial bid of 100 and a bid increment of 10. We then call the BuildAuctionInfo function with this object to create a new AuctionInfo object containing the same information. Finally, we print out the various fields of the AuctionInfo object using standard output. It is not possible to determine which package library these classes belong to without additional context.
