Introduction
I have used Visual Studio 2012 for debugging purpose. But you can use any version of visul studio as per your availability.
using System; class Program { static void Main(string[] args) { char gender; //Reading gender from user Console.WriteLine("Enter gender (M/m or F/f): "); gender = Convert.ToChar(Console.ReadLine()); // checking vowel and consonant switch (gender) { case 'M': case 'm': Console.WriteLine("MALE"); break; case 'F': case 'f': Console.WriteLine("FEMALE"); break; default: Console.WriteLine("Unspecified Gender"); break; } Console.ReadLine(); } }
