2,028 PointsDefine an Eat method invincible Console.WriteLine(); input?
Hello, I have an issue with Define Eat method string challenge.
static string Eat(string first, string second) { Console.WriteLine($"I think {first} and {second} are tasty!"); return Console.ReadLine(); }
static void Main(string[] args) { Console.WriteLine(Eat("apples", "blueberries")); Console.WriteLine(Eat("carrots", "daikon")); }
However it prints out the following words: I think eggs and falafel are tasty!
Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object. at Test.Main(String[] args) in /workdir/Test.cs:line 20
Is there a bug in the system or have I written the code wrongly? I gave it a testrun with the exact same code on VSCODE and it prints out
I think apples and blueberries are tasty!

should return a string ...", but this code is writing the string to the console instead.
Also, the instructions don't ask for anything to be read from the console.

2,028 PointsSo I should not add a console?
Like this for example:

231,210 PointsVery close! Now you're only missing the exclamation point (!) at the end of the string.
