Question

Provide immediate feedback for each mistyped sentence. To do so, modify the Test class’s present_test method so that it informs the player a mistake has been made, then display the challenge sentence followed by the player’s sentence so the player can determine where the error lies.

# Script Name: TypingChallenge.rb
# Version:     1.0
# Author:      Jerry Lee Ford, Jr.
# Date:        March 2010
# 
# Description: This Ruby script demonstrates how to apply conditional logic 
#              in order to analyze user input and control script execution 
#              through the development of a computer typing test that
#              evaluates the player's typing skills.

    STDIN.gets  #Execute the STDIN class's gets method to pause script

# Main Script Logic -------------------------------------------------------

#Initialize global variable that will be used to keep track of the number
#of correctly retyped sentences
$noRight = 0

Console_Screen = Screen.new  #Instantiate a new Screen object
Typing_Test = Test.new        #Instantiate a new Test object

#Execute the Test object's display_greeting method

answer = STDIN.gets  #Collect the player's response
answer.chop!  #Remove any extra characters appended to the string
  
#Loop until the player enters y or n and do not accept any other input.
until answer == "y" || answer == "n"
