                Console.Write("Delivery to {0} ok. ", entryZip);

        }
        if (!zipFound)
            Console.WriteLine("no delivery to {0}. ",entryZip);

        Console.ReadKey();
    }
}

}

//I cant understand why the zipFound is bool zipFound = false; //anyone can explain it to me thanks :)

  • I recommend stepping through with the [debugger](https://stackoverflow.com/questions/25385173/what-is-a-debugger-and-how-can-it-help-me-diagnose-problems). I also recommend reading Eric Lippert's [How to debug small programs](https://ericlippert.com/2014/03/05/how-to-debug-small-programs/). – ProgrammingLlama Apr 07 '20 at 08:23

    Please share a [mcve] that does _not_ read from the console so we can be confident what the value of `entryZip` is. – mjwills Apr 07 '20 at 08:25

    Note that the `zipFound = true;` should **almost certainly** be inside the `if` a few lines up. Otherwise there is no point this code being inside a loop (since it will only ever execute 0 or 1 times). – mjwills Apr 07 '20 at 08:27
  • `bool zipFound = false;` is there to ensure that you enter the loop. If you defaulted it to `true` the loop would never be entered. – mjwills Apr 07 '20 at 08:27
