Proposed exercise
Create a program to ask the user for a symbol and answer if it is a (lowercase) vowel, a digit, or any other symbol, using "if".
Output
Solution
using System; public class Vowel { public static void Main() { char symbol; Console.Write("Enter a symbol: "); symbol=Convert.ToChar(Console.ReadLine()); if ((symbol == 'a') || (symbol == 'e') || (symbol == 'i') || (symbol == 'o') || (symbol == 'u')) Console.WriteLine("It's a lowercase vowel."); else if ((symbol >= '0') && (symbol <= '9')) Console.WriteLine("It's a digit."); else Console.Write("It's another symbol."); } }
