Required Assignment: create a reference and a pointer (C++)a. Create a better dice game. Each player (user or computer) has 2 dices. And you are required to use 1 reference variable and 1 pointer variable. You need to indicate where you use these in your code. b. The winning rule is as follows: if 2 dices of a player have the same value as a pair of 6 and the other player does not have a pair of value then a pair of value will win. So, 5&5 will beat 6&4 because 5&5 is a pair. If both players have pairs, (user and computer), the higher pair will win. For example, 6&6 will beat any pair. If both players do not have pair, then higher total points will win. c. The output of the program may be like the following:Welcome to the dice ware game. You have 100 in your game purse. Enter a bet amount to play (0 means exit the program): 10You have 5 & 5 computer has is 3 & 4You won 10 dollars!Your game purse now has 110 dollarsEnter a bet amount to play (0 means exit the program): 5You have 6 & 4 computer has is 1 & 1You lost 5Your game purse now has 105 dollarsEnter a bet amount to play (0 means exit the program): 10You have 1 & 2 computer has is 3 & 4You lost 10Your game purse now has 95 dollarsEnter a bet amount Enter a bet amount to play (0 means exit the program): 0You choose to exit the program.
