How to write a program to check whether the input alphabet is a vowel or not using switch case.

Solution (C#)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threadings Tasks;
namespace IsVowel
{
class Program
{
//create the structure where we will contain statistic information about vowels
public struct Vowel
{
private int[] Position;  // positions of vowel in the string
private int count;  // number of vowel entries into string
private char symbol;  // vowel
public Vowel(char s)  // initial constructor
{
symbol = s;
count = 0;
Position = new int[256];
}
public void Add(int p)  // to add the information about vowels entry
{
count++;
Position[count - 1] = p;
}
public int[] Positions  // return array with positions
{
get { return Position; }
}
public char Symbol  // return vowel symbol
{
get { return symbol; }
}
public int Count  // return number of vowels entries
{
get { return count; }
}
}

}

static void Main(string[] args)

{

// vowels structures for gathering statistic

Vowel vowelA, vowelE, vowelI, vowelO, vowelU, vowelY;

vowelA = new Vowel('a');

vowelE = new Vowel('e');

vowelI = new Vowel('i');

vowelO = new Vowel('o');

vowelU = new Vowel('u');

vowelY = new Vowel('y');

Console.WriteLine("Enter char string:");

// enter string

string str = Console.ReadLine();

// convert string symbols to low case

str = str.ToLower();

// check string chars

for(int i=0; i<str.Length; i++)

{

switch (str[i])

{

case 'a': vowelA.Add(i);

break;

case 'e': vowelE.Add(i);

break;

case 'i': vowelI.Add(i);

break;

case 'o': vowelO.Add(i);

break;

case 'u': vowelU.Add(i);

break;

case 'y': vowelY.Add(i);

break;

}

}

// printing results

Console.WriteLine("The statistic of vowels in the string is:");

Console.WriteLine("a - {0}\t e - {1}\t i - {2}\t o - {3}\t u - {4}\t, y - {5}\n",

vowelA.Count, vowelE.Count, vowelI.Count, vowelO.Count, vowelU.Count,

vowelY.Count);

Console.ReadKey();

}

}
