It will return anewly created PurchaseOrder object holding that information if they are valid:quantity and cost per item cannot be negative and the description cannot be empty or blank(s). When it is invalid, it will return NULL to indicate that it cannot create such PurchaseOrder object.PurchaseOrder createPurchaseOrder(int quantity, double costPerItem, string description){ if(quantity < 0 || costPerItem < 0.0 || description == "") return NULL; else { PurchaseOrder p = new PurchaseOrder(quantity,costPerItem,description); return p; }}what's the issue with this functionand how to rewrite it FileEditSelectionViewGoRun Terminal Help.cpp - Visual Studio CodeEXPLORERC+ user.cppC+.cppG degree.cppG midtermpractice4.cppG• midtempractice3.cppG showHelp (1).cpp •...6V OPEN EDITORS 6 UNSAVEDD: > G .cpp > O createPurchaseOrder(int, double, string)PurchaseOrder createPurchaseOrder(int quantity, double costPerItem, string description){if(quantity < e || costPerItem < 0.0 || description == "")1C+ user.cpp D:\X & .cpp D:\23G+ degree.cpp D:\return NULL;G+ midtermpractice4.cpp D:\elseTG+ midtempractice3.cpp D:\G• showHelp (1).cpp D:\PurchaseOrder p = new PurchaseOrder(quantity,costPerItem, description);7G+ getnumlist (1).cpp D:\E #include Untitled-3return p;E #include Untitled-110}11v NO FOLDER OPENEDYou have not yet opened a folder.Open FolderE Code +v MO ^ xPROBLEMSOUTPUTDEBUG CONSOLETERMINALYou can clone a repository locally.Windows PowerShellCopyright (C) Microsoft Corporation.
