date time excises

Please help me do my code
Note : I’m new c# learning

I can’t do it

Please help me

DateTime.Now returns the current date and time from ur pc

You want to add 3 Days to the date you input not to the current date

and this is how you format your date date.ToString("yyyy-MM-dd")

like this?

ToString returns a string, and u have to assign that string to a variable or use it directly in your Console.WriteLine

thank you so much @TheRanger
