<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().

Answer:
An error will be occurred here. In C++ a function must be like
returntype function_name(){
}
but the functions in given class does not have returntype given. So there will be a syntax error.
If the returntype is defined then the code does not show any output since nothing is printed in the main function.
