C# program to count vowels in string

You need to check for vowels and consonants, but don't forget to check for upper and lower case.

To count vowels, check the "aeiou" characters individually, i.e.

if (myStr[i] == 'a' || myStr[i] == 'e' || myStr[i] == 'i' || myStr[i] == 'o' || myStr[i] == 'u' || myStr[i] == 'A' || myStr[i] == 'E' || myStr[i] == 'I' || myStr[i] == 'O' || myStr[i] == 'U') {
   vowel_count++;
}

Example

Here is the code to count the number of vowels in a string.

Live Demo

using System;
public class Demo {
   public static void Main() {
      string myStr;
      int i, len, vowel_count, cons_count;
      myStr = "Avengers";
      vowel_count = 0;
      cons_count = 0;
      // find length
      len = myStr.Length;
      for(i=0; i<len; i++) {
         if(myStr[i] ==&#39;a&#39; || myStr[i]==&#39;e&#39; || myStr[i]==&#39;i&#39; || myStr[i]==&#39;o&#39; || myStr[i]==&#39;u&#39; || myStr[i]==&#39;A&#39; || myStr[i]==&#39;E&#39; || myStr[i]==&#39;I&#39; || myStr[i]==&#39;O&#39; || myStr[i]==&#39;U&#39;) {
            vowel_count++;
         } else {
            cons_count++;
         }
      }
      Console.Write("Vowels in the string: {0}", vowel_count);
   }
}

Output

Vowels in the string: 3
