Game Description In this game, the user plays against the computer. The two players (the user and the computer) take turns in rolling two die. Both the players race to reach a score of 50. The first player who scores 50 or more points wins. The game starts with the user’s turn. Each turn, a player repeatedly rolls two die until either a 1 is rolled on any of the two die or the player decides to "hold". The following are the rules of the game:
If the player does not roll a 1 on any of the two die, the sum of the two die is added to his turntotal and the player's turn continues.
If the player rolls a 1 on one of the two die, he score nothing and it becomes the next player's turn.
If two 1s are rolled, the player’s entire total score is lost, and the turn ends.
If a player chooses to "hold", his turn-total is added to his/her total score, and it becomes the next player's turn.
The first player to score 50 or more points wins. Program Requirements Your program should be resilient to having wrong input. The program input should not be case sensitive. Therefore, if the user enters an input character (e.g., 'H' for hold), the program should accept and interpret both small and capital characters in the same way (e.g., both 'H' and 'h' are accepted as the input to hold). You can make the computer player follow any intelligent strategy to win. However, to simplify the requirements, you can make it have the strategy of making random choices with 50% chance for rolling and 50% for holding.
For example, the following C++ statement will set the computer response to 'R' for rolling, or 'H' for holding with 50% probability for each: response = rand()%2? 'R' : 'H';
Pseudo Code The following shows a sample pseudo code for this game program:
Initialize turnTotal, userScore and computerScore to zero Initialize turn to user
Loop until one of the scores reaches 50 or higher
If user turn Call function to handle the user turn
Else Call function to handle the computer turn Set turnTotal = 0
End loop
If userScore 50 User wins
Else Computer wins
Endif
Handling the user turn:
Display the current scores User inputs ‘R’ to start rolling Loop while the user input is ‘R’ and it is still his turn Roll the two die
If both rolls are 1 Reset the userScore to zero Change the turn to computer
Else if one of the rolls is 1 Change the turn to computer
Else Add the two die rolls to turnTotal and display turnTotal Ask the user if he wants to “Hold” or “Roll” again
Endif
If the users entered “Hold” Add the turnTotal to userScore Change the turn to Computer
Endif
End loop
Handling the computer turn:
This is very similar to handling the user turn except that instead of reading the user’s input, the computer generates his choices automatically.
