using System;

class RandomQuotesProgram
{
    static void Main(string[] args)
    {
        Console.WriteLine("Welcome to the Random Quotes Program!");

        // Array of quotes
        string[] quotes = new string[]
        {
            "The only limit to our realization of tomorrow is our doubts of today. - Franklin D. Roosevelt",
            "In the middle of every difficulty lies opportunity. - Albert Einstein",
            "Success is not final, failure is not fatal: It is the courage to continue that counts. - Winston Churchill",
            "Do what you can, with what you have, where you are. - Theodore Roosevelt",
            "Act as if what you do makes a difference. It does. - William James",
            "Life is what happens when you're busy making other plans. - John Lennon",
            "The way to get started is to quit talking and begin doing. - Walt Disney",
            "Believe you can and you're halfway there. - Theodore Roosevelt",
            "You miss 100% of the shots you don’t take. - Wayne Gretzky",
            "It always seems impossible until it’s done. - Nelson Mandela"
        };

        while (true)
        {
            Console.WriteLine("\nPress 'Enter' to get a random quote, or type 'exit' to quit.");
            string userInput = Console.ReadLine();

            // Check if the user wants to exit
            if (userInput.Trim().ToLower() == "exit")
            {
                Console.WriteLine("Goodbye!");
                break;
            }

            // Generate a random quote
            string randomQuote = GetRandomQuote(quotes);
            Console.WriteLine($"\nRandom Quote:\n\"{randomQuote}\"");
        }
    }

    static string GetRandomQuote(string[] quotes)
    {
        // Generate a random index based on the quotes array length
        Random random = new Random();
        int index = random.Next(quotes.Length);
        return quotes[index];
    }
}

Explanation

1. Introduction and Quote List:
   • The program starts by greeting the user and explaining how to interact with it.
   • It defines a string[] array to store the quotes.

   string[] quotes = new string[]
   {
       "The only limit to our realization of tomorrow is our doubts of today. - Franklin D. Roosevelt",
       "In the middle of every difficulty lies opportunity. - Albert Einstein",
       "Success is not final, failure is not fatal: It is the courage to continue that counts. - Winston Churchill",
       ...
   };
   

2. Generating a Random Quote:
   • The GetRandomQuote method generates a random index using the Random class.
   • The index corresponds to a position in the quotes array, and the quote at that index is returned.

   static string GetRandomQuote(string[] quotes)
   {
       Random random = new Random();
       int index = random.Next(quotes.Length);
       return quotes[index];
   }
   

3. User Interaction:
   • The program runs in a while (true) loop to allow the user to request multiple quotes.
   • The user presses “Enter” to generate a random quote or types “exit” to quit the program.

   while (true)
   {
       Console.WriteLine("\nPress 'Enter' to get a random quote, or type 'exit' to quit.");
       string userInput = Console.ReadLine();
   
       if (userInput.Trim().ToLower() == "exit")
       {
           Console.WriteLine("Goodbye!");
           break;
       }
   
       string randomQuote = GetRandomQuote(quotes);
       Console.WriteLine($"\nRandom Quote:\n\"{randomQuote}\"");
   }
   

4. Program Exit:
   • The loop exits when the user types “exit”, displaying a goodbye message.

   if (userInput.Trim().ToLower() == "exit")
   {
       Console.WriteLine("Goodbye!");
       break;
   }
   

Sample Run

Run the program:

Welcome to the Random Quotes Program!

Press 'Enter' to get a random quote, or type 'exit' to quit.
[User presses Enter]

Random Quote:
"The only limit to our realization of tomorrow is our doubts of today. - Franklin D. Roosevelt"

Press 'Enter' to get a random quote, or type 'exit' to quit.
[User presses Enter]

Random Quote:
"In the middle of every difficulty lies opportunity. - Albert Einstein"

Press 'Enter' to get a random quote, or type 'exit' to quit.
exit
Goodbye!

Features

1. Predefined Quote List:
   • The program uses a string[] array to store quotes, which can be easily expanded.
2. Random Selection:
   • The Random class ensures a random quote is selected every time the user presses “Enter.”
3. Interactive Loop:
   • Allows the user to keep generating quotes until they decide to exit.
4. User-Friendly Exit:
   • The user can type “exit” at any time to quit the program gracefully.

Ideas

1. Add More Quotes:
   • Expand the quotes array with more inspiring or humorous quotes.
2. Save Quotes to File:
   • Save all displayed quotes to a file for the user to review later.

   using System.IO;
   File.AppendAllText("quotes_log.txt", randomQuote + Environment.NewLine);
   

3. Categories:
   • Organize quotes into categories (e.g., Inspirational, Humorous) and let the user choose a category.

   Console.WriteLine("Choose a category: Inspirational, Humorous, etc.");
   

4. Graphical Interface:
   • Use Windows Forms or WPF to create a graphical version of the program.
5. Dynamic Quote Source:
   • Fetch quotes from an API like quotable.io or a local database for more variety.

This C# Random Quotes Program is a fun and engaging way to practice working with arrays, loops, and the Random class.
