Answer 2

char letter;
Console.WriteLine("Type a letter");
string Ltr = Console.ReadLine();
Letter= char.Parse(Ltr);

Console.WriteLine (" The letter ;{0} , is a vowel" ,letter);

case'a': case' e': case'i':case 'o':case 'u':

Console.WriteLine (" {0} is a lowercase vowel" ,letter);
case'A': case' E': case'I':case 'O':case 'U':

Console.WriteLine (" {0} is a uppercase vowel" ,Letter);
