Question

Write a program that takes in a line of text as input, and outputs that line of text in reverse. The program repeats, ending when the user enters "Quit", "quit", or "q" for the line of text.
Ex: If the input is:

Hello there
Hey
quit
then the output is:

ereht olleH
yeH

I can't figure out how to make this code. If anyone could help I would appreciate it.

Answer 1

Answer:

using System;

public class Program

{

public static void Main()

{

String input ;

while(true)

{

 input = Console.ReadLine();

 if(input.Equals(""quit""))

 break;

 Reverse_String(input);

}

return;

}

static void Reverse_String(string input_text)

{

   char[] text = input_text.ToCharArray();

   Array.Reverse(text);

   Console.WriteLine(text);

}

Explanation:

In the above program a separate function is written to reverse the string.

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.

In the main(), the input is obtained from the console and it is passed to the reversestring().

Answer 2

Answer:

while True:

       values = str(input())

       if values == 'quit' or values == 'Quit' or values == 'q':

              break

       print(values[::-1])

Explanation:

Firstly, save the code on a folder and save it with any name but it must end with .py . Example data.py, save.py, reverse.py etc. Afterward, you run the code on the python shell . On the shell type  "python saved filename(save.py or data.py, reverse.py)"

I used python to solve the problem. Normally, if one wants to iterate or loop through a particular function or code you  use a loop. In this case i used a while loop.

Using while True , the values will always loop since True is always True.

values = str(input()) , This code make sure the input is always a string, since we want only text.

if values == 'quit' or values == 'Quit' or values == 'q':  , This code means the values should quit or stop working if the user input any of the text "quit" or "Quit" or "q".

print(values[::-1]) ,  This code means the input text should be reversed. example joy will be yoj

Generally, the code will always loop and print the reverse of the text unless it encounter any input value like "quit" or "Quit" or "q"
