C# Program to Check Vowels or Consonants

In this article, I will be writing a C# Program to check vowels or consonants. I will be explaining the whole program stepwise. It is a common interview question for freshers.

Program Overview

We are going to solve a commonly asked question in C# Programming. We are going to write a C# Program to check Vowels or Consonants in the entered alphabets. I will be using the switch-case method in C# to check vowels and consonants.

C# Program to Check Vowels or Consonants

Here’s the C# Program to check Vowels or Consonants:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
  
public   class exercise16
   {
       static void Main(string[] args)
       {
           char ch;
           Console.Write("\n\n");
           Console.Write("Vowel or Consonant checker tool\n");
           Console.Write("-----------------------------------------------------");
           Console.Write("\n\n");
 
           Console.Write("Please Enter an Alphabet (A-Z or a-z) : ");
           ch = Convert.ToChar(Console.ReadLine().ToLower());
           int i=ch;
           if(i>=48 && i<=57)
           {
            Console.Write("Err! Please enter an alphabet not a number."); 
            }
           else
           {           
           switch (ch)
           {
                case 'a':
                   Console.WriteLine("Entered alphabet is vowel");
                   break;
               case 'i':
                   Console.WriteLine("Entered alphabet is vowel");
                    break;
               case 'o':
                   Console.WriteLine("Entered alphabet is vowel");
                   break;
               case 'u':
                   Console.WriteLine("Entered alphabet is vowel");
                   break;
               case 'e':
                   Console.WriteLine("Entered alphabet is vowel");
                   break;
               default:
                   Console.WriteLine("Entered alphabet is a Consonant");
                   break;
            }
            }
           Console.ReadKey();
       }
   }

Program Output

Here’s the output of the above program:
