<u>Answer:</u>
<em>using System;
</em>
<em>public class Program
</em>
<em>{
</em>
<em> public static void Main()
</em>
<em> {
</em>
<em> String input ;
</em>
<em> while(true)
</em>
<em> {
</em>
<em> input = Console.ReadLine();
</em>
<em> if(input.Equals(""quit""))
</em>
<em> break;
</em>
<em> Reverse_String(input);
</em>
<em> }
</em>
<em> return;
</em>
<em> }
</em>
<em>static void Reverse_String(string input_text)
</em>
<em>{
</em>
<em> char[] text = input_text.ToCharArray();
</em>
<em> Array.Reverse(text);
</em>
<em> Console.WriteLine(text);
</em>
<em>}
</em>
<u>Explanation:</u>
<em>In the above program a separate function is written to reverse the string.</em>
This method takes the string as an argument and place it in a array and then use the built-in function reverse and print the reversed string in the console.
<em>In the main(), the input is obtained from the console and it is passed to the reversestring().
</em>
Answer:
Explanation:
a. In this scenario, the best solution would have an Object of Traditional Books, CD, Music, Bookstore and Customer.
b. All five objects would be able to be called by the main program loop and the Customer Object would call upon and use either the Books or CD object, While the Bookstore object would call upon all of the other objects.
c. Both the Bookstore object and Customer object will "have" other objects as the Bookstore needs to hold information on every Book or CD in the Inventory. While the Customer object would call upon the Book and CD object that they are purchasing.
d. The Music Object will extend the CD object and use information on the CD object as its parent class.
e. Since the Music Object extends the CD object it is also considered a CD since it is in CD format like the Books on CD and therefore is both objects.
