Exercise 5.27:

Function CountDV


Objetive:

Create a function that calculates the amount of numeric digits and vowels that a text string contains. It will accept three parameters: the string that we want to search, the variable that returns the number of digits, and the number of vowels, in that order). The function should be called "CountDV". Use it like this:

CountDV ("This is the phrase 12", ref amountOfDigits, ref amountOfVowels)

In this case, amountOfDigits would be 2 and amountOfVowels would be 5


Source Code:


using System;
public class CDV
{
    public static void CountDV(string answer, ref int amountOfDigits, ref int amountOfVowels)
    {
        amountOfDigits = 0;
        amountOfVowels = 0;

        for (int i = 0; i < answer.Length; i++)
        {
            switch (answer.Substring(i, 1).ToLower())
            {
                case "a":
                case "e":
                case "i":
                case "o":
                case "u":
                    amountOfVowels++;
                    break;
                case "0":
                case "1":
                case "2":
                case "3":
                case "4":
                case "5":
                case "6":
                case "7":
                case "8":
                case "9":
                    amountOfDigits++;
                    break;
            }
        }
    }

    public static void Main()
    {
        int amountOfDigits = 0;
        int amountOfVowels = 0;

        CountDV("This", ref amountOfDigits, ref amountOfVowels);

        Console.WriteLine(amountOfDigits);
        Console.WriteLine(amountOfVowels);
    }
}
