✅ User Input

Hello, if there a way to stop my program from crashing when the user inputs a letter instead of an integer? I tried searching online but I couldn't find an answer, I may be just phrasing it wrong. Thank you

✅ Random character generator

Hello, as a beginner, I am currently working on making a simple lottery simulator. However, I didn't know how to generate a sequence of 8 letters and numbers. Naturally, I searched it up and I got the answer. But copying chunks of code wouldn't help me learn and I can't seem to wrap my head around how this works. I understand the variables, but I can't just seem to understand what the variable i does and why i = 0. Would anyone be kind enough to explain the for statement and what each argument does. Thank you so much 🙏

var chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
            var stringChars = new char[8];
            var randomNumber = new Random();

            for (int i = 0; i < stringChars.Length; i++)
            {
                stringChars[i] = chars[randomNumber.Next(chars.Length)] ;
            }

            var finalString = new String(stringChars);

            Console.WriteLine(finalString);
