C#: Prompt the user to input a sentence. Once you have their sentence, figure out how many vowels (a, e, i, o, u) and how many consonants are in the sentence. Output the total number of consonants and vowels in the following format (2 separate lines and the format specifier should be general with 0 decimal places!)

There were 5 vowels in the sentence.
There were 15 consonants in the sentence.

Answer 1

using System;

class MainClass {
  public static void Main (string[] args) {

        Console.WriteLine("Enter your sentence: "); 
        string sentence = Console.ReadLine().ToLower(); 

        int vowelCount = 0;
        int consonantsCount = 0;
        
        for (int i = 0; i < sentence.Length; i++) {
                char c = sentence[i];
                if (char.IsLetter(c) && (c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u')) {
                        vowelCount++;
                } else if (char.IsLetter(c)) {
                        consonantsCount++;
                }
        }

        Console.WriteLine ("There were " + vowelCount + " vowels in the sentence.");
        Console.WriteLine ("There were " + consonantsCount + " consonants in the sentence.");
  }
}
