Program to Count the Number of Vowels - (C# Basic Programs)

Counting the number of vowels in a given string is a common programming exercise that helps improve problem-solving skills. In this tutorial, we will discuss a program in C# to count the number of vowels in a given string.

Syntax

The syntax for counting the number of vowels in a string in C# is as follows:

int vowelCount = 0;
string input = "example string";

foreach (char c in input) {
    if ("AEIOUaeiou".IndexOf(c) != -1) {
        vowelCount++;
    }
}

Console.WriteLine(vowelCount);

Example

using System;

namespace VowelCount
{
    class Program
    {
        static void Main(string[] args)
        {
            int vowelCount = 0;
            Console.WriteLine("Enter a string:");
            string input = Console.ReadLine();
            foreach(char c in input)
            {
                if("AEIOUaeiou".IndexOf(c)!=-1)
                {
                    vowelCount++;
                }
            }
            Console.WriteLine("Number of vowels: " + vowelCount);
        }
    }
}

Output:

Enter a string:
This is an example string
Number of vowels: 7

Explanation

The program uses a foreach loop to iterate through each character in the input string. It then checks if the character is a vowel by using the IndexOf() method to see if the character exists in the string of vowels. If the character is a vowel, the vowel count is incremented. Finally, the program displays the number of vowels counted.

Use

Counting the number of vowels in a given string is a good exercise to improve C# programming skills. This program demonstrates the use of loops, conditional statements, and string manipulation to perform a useful task.

Summary

In this tutorial, we discussed a program in C# to count the number of vowels in a given string. We covered the syntax, example, explanation, and use of counting vowels in C#. By practicing similar exercises, programmers can improve their problem-solving skills and become better equipped to tackle more complex programming challenges.
