The problem
Write a console-based application that asks the user to type a
vowel from the keyboard. If the character entered is a vowel,
display "OK"; if it is not a vowel, display an error message.
Be sure to allow both uppercase and lowercase vowels. Th e
program continues until the user types '!'.
I been doing it for last 30 minutes, and I just cant figure out how to do it....
This is as far as I got
int count = 0;
double userInput;
string userInputString;
Console.WriteLine("Enter vowel");
userInputString = Console.ReadLine();
userInput = Convert.ToChar(userInputString);
Help?
