Method1: C# program to count vowels and consonants in a string

Let’s start with a simple C# program that count vowels and consonants in a string. Below is the complete code, and we’ll break it down step by step.

using System;

class Program
{
    static void Main()
    {
        Console.WriteLine("Enter a string:");
        string input = Console.ReadLine();

        int vowelCount = CountVowels(input);
        int consonantCount = CountConsonants(input);

        Console.WriteLine($"Vowel count: {vowelCount}");
        Console.WriteLine($"Consonant count: {consonantCount}");
    }

    static int CountVowels(string str)
    {
        int count = 0;
        foreach (char c in str.ToLower())
        {
            if ("aeiou".Contains(c))
            {
                count++;
            }
        }
        return count;
    }

    static int CountConsonants(string str)
    {
        int count = 0;
        foreach (char c in str.ToLower())
        {
            if (char.IsLetter(c) && !"aeiou".Contains(c))
            {
                count++;
            }
        }
        return count;
    }
}

Output:

Enter a string:
abcdefghijklmnopqrstuvwxyz
Vowel count: 5
Consonant count: 21

Code Explanation:

The program starts by prompting the user to enter a string. The input is then stored in the input variable.
The CountVowels method counts the number of vowels in the given string. It converts the input string to lowercase to ensure case-insensitive counting.
Similarly, the CountConsonants method counts the number of consonants. It checks if a character is a letter and not a vowel.
After counting, the program displays the results to the user.

Method2: Count vowels and consonants in a string using LINQ

Let’s add another method to count vowels and consonants in a string using a slightly different approach. This time, we’ll use LINQ (Language Integrated Query) to demonstrate an alternative method.

using System;
using System.Linq;

class Program
{
    static void Main()
    {
        Console.WriteLine("Enter a string:");
        string input = Console.ReadLine();

        int vowelCount = CountVowels(input);
        int consonantCount = CountConsonants(input);

        Console.WriteLine($"Vowel count: {vowelCount}");
        Console.WriteLine($"Consonant count: {consonantCount}");
    }

    static int CountVowels(string str)
    {
        // Using LINQ to count vowels
        int vowelCount = str.ToLower().Count(c => "aeiou".Contains(c));
        return vowelCount;
    }

    static int CountConsonants(string str)
    {
        // Using LINQ to count consonants
        int consonantCount = str.ToLower().Count(c => char.IsLetter(c) && !"aeiou".Contains(c));
        return consonantCount;
    }
}

Compile and run the above program to test it with different strings. This approach allows you to see the results for various inputs.

Output:

Enter a string:
This is a simple Hello World.
Vowel count: 8
Consonant count: 15

Conclusion

Counting vowels and consonants in a string is a basic but powerful skill in programming. This article has provided a clear and practical method for implementing such functionality.

Feel free to modify and expand the code to suit your needs. Happy coding!
