This will come with a small main() function, and a function to parse user input into an array of ranges for dice. The format expected for user input is either "Xdy", where x and y and integers or +x" where x is an integer The format "xdy" indicates rolling x y-sided dice, and the format "+x" indicates that x should be added to the total of the dice roll. For example: "2d6+1" represents rolling two 6-sided dice then adding one to the result. In this example, the minimum and maximum possible rolls are 3 and 13 respectively. Multiple additions or dice can be added to the roll by spacing; for example: "2d4 +1 3d6 +4" represents rolling two 4-sided dice, three 6-sided dice, and adding 5 to the total Your program must have the following 1) Create a Dice class that contains the following members a) Two private integer variables to store the minimum and maximum roll possible b) Two constructors (a default constructor and one that takes two integers to initialize the dat:a members that store the min/max possible values of rolls) c) Create a roll() function that returns a random number uniformly distributed between the minimum and maximum possible roll values 2) Create a dynamic array of objects of the Dice class, and use this to compute the statistics (Don't forget to properly delete the array when you are done with it.) After the single getline() in the sample code, your program should ask the user how many rounds they wish to roll. You may assume that the user does not enter a malicious input Then, roll all the dice this number of times and display the following information (following the format and order shown in the examples) 1) A sample roll from the entered line (this roll is not counted in min/max/average statistics) 2) The minimum roll observed 3) The maximum roll observed 4) The average value of all the rolls  Problem B: Dice rolling class (20 points) Start by downloading the "dice.cpp" file from the webpage.
