Identifying Vowels, Digits, and Symbols in C#

In this exercise, we will create a C# program that classifies a user-provided character into one of four categories: an uppercase vowel, a lowercase vowel, a digit, or any other symbol. The program will analyze the input using `if` statements and provide the appropriate classification. This exercise helps in understanding conditional statements, character handling, and logical operations in C#.

C# Basic Data Types Overview

Objective

1. Prompt the user to enter a single character.
2. Use `if` statements to check if the character is:
- An uppercase vowel (`A, E, I, O, U`).
- A lowercase vowel (`a, e, i, o, u`).
- A digit (`0-9`).
- Any other symbol.
3. Display a message indicating the classification of the input.
4. Ensure the program handles non-character inputs properly.

Write a C# program to ask the user for a symbol and answer if it is an uppercase vowel, a lowercase vowel, a digit, or any other symbol, using "if".

Example C# Exercise

 Copy C# Code 
using System;

class Program
{
    static void Main()
    {
        // Ask the user to enter a single character
        Console.Write("Enter a single character: ");
        char input = Console.ReadKey().KeyChar;
        Console.WriteLine(); // Move to the next line

        // Check if the input is an uppercase vowel
        if (input == 'A' || input == 'E' || input == 'I' || input == 'O' || input == 'U')
        {
            Console.WriteLine("The character is an uppercase vowel.");
        }
        // Check if the input is a lowercase vowel
        else if (input == 'a' || input == 'e' || input == 'i' || input == 'o' || input == 'u')
        {
            Console.WriteLine("The character is a lowercase vowel.");
        }
        // Check if the input is a digit (0-9)
        else if (input >= '0' && input <= '9')
        {
            Console.WriteLine("The character is a digit.");
        }
        // If it's neither a vowel nor a digit, classify it as another symbol
        else
        {
            Console.WriteLine("The character is another type of symbol.");
        }
    }
}

 Output

//Example 1: User enters 'E'
Enter a single character: E
The character is an uppercase vowel.

//Example 2: User enters 'i'
Enter a single character: i
The character is a lowercase vowel.

//Example 3: User enters '5'
Enter a single character: 5
The character is a digit.

//Example 4: User enters '#'
Enter a single character: #
The character is another type of symbol.
