The d method determines whether a variabie exists, returning a value of true if the variable is found. 19.

Reinforcement Exercises The following exercises are designed to further your understanding of Ruby programming by challenging you to make improvements tothe chapters game project, the Rock, Paper, Scissors game. 1. Currently, the Game class's get player move method uses a regular expression to validate the player's moves of Rock. Paper, or Scissors, rejecting any input other than one of these words. Making the player enter entire words takes time and can lead to typos, however. Simplify game play by modifying the get player move method to also allow single- character input in the form of R, P, and S. Make sure you accommodate both uppercase and lowercase input. 2. The game allows players to play an unlimited number of times. To help them keep track of how many times they have played, modify the game by adding a global variable named Sgamecount at the beginning of the program's Main Script Logic area, assigning it an initial value of 0. Next add a method named game count and set it to increment the value of sgamecoun t each time it is executed. Lastly, add a statement to the play game method that executes the 290 CHAPTER 8 Object-oriented Programming 17. A(n) variable's scope is accessible to all instances of the same class a. Local b.
