Return Vowels in C#

[DotnetBeginner]

I am trying to return num of vowels present in a string using c#. I am
not getting that. Can any body have any ideas

Appreciated.

Remember that a string is just a collection of characters. Once you
realize that, it should be pretty straightforward. I won't spoil the
fun of your homework assignment by going any further...

Of course, your definition of what a vowel is may differ - whether
it's just aeiouAEIOU, or if you're dealing with accented and other
special letters...

Use character array and try it...........still u dont get it..then i will help in detail

I would do it the following way :

1. Create a char array comprising of the vowel letters.
2. Run a While loop searching within the string from position 0 and
looping each time you find a vowel, this time starting with the
position at which find was successful.

Happy Homework-ing !!

Hi Guys,

The easy way for beginners to count vowels in a string is

using System;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApplication3
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Enter the string");
string chr = Console.ReadLine().ToLower();
char ch2 = 'a';
char ch3 = 'e';
char ch4 = 'i';
char ch5 = 'o';
char ch6 = 'u';
int j = 0;

foreach (char ch in chr)
{

if (ch == ch2)

j++;
else
if (ch == ch3)

j++;
else
if (ch == ch4)
j++;
else
if (ch == ch5)
j++;
else
if (ch == ch6)
j++;
}
Console.WriteLine(j);

}
}
}

DAMN. Endless for-else loops and an undeclared variable. sweet.

At Least tried will learn soon proper coding, like seniors.

Use regular expressions

void ShowVowels(string input)
{
string str = "(a|e|i|o|u)";
Regex expression = new Regex(str);
if (expression.IsMatch(input))
{
MatchCollection value = expression.Matches(input);
foreach (Match m in value)
{
Console.WriteLine(m.Value);
}
}
}

Here you go.

using System;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApplication3
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Enter the string");
            string chr = Console.ReadLine().ToLower();
            char ch2 = 'a';
            char ch3 = 'e';
            char ch4 = 'i';
            char ch5 = 'o';
            char ch6 = 'u';
            int j = 0;

            foreach (char ch in chr)
            {

                if ((ch == ch2)|(ch == ch3)|(ch == ch4)|(ch == ch5)|(ch == ch6))
                     j++;
              }
            Console.WriteLine(j);
        }
    }
}

This is the solution I sent on the 20th, in response to Sushma's email
to me :

---
private void FindVowels(string input)
{
char[] vowels = new Char[] { 'a', 'e', 'i', 'o', 'u' };
int pos = 0;
bool found = false;
do
{
pos = input.IndexOfAny(vowels, pos);
if(pos > -1)
{
pos += 1;
Console.WriteLine("Vowel found at position: {0}", pos.ToString
());
if(!found)
found = true;
}
} while(pos > -1);

if(found == false)
Console.WriteLine("No Vowels found in the supplied string.");
}

Comments/improvements are appreciated.
