Programming Exercise 22 prompted the user to input the number of times the dice were to be rolled and the desired sum, and the program output the number of times the desired sum occurred. Modify Programming Exercise 22 as follows: Suppose you roll 4 dice 1000 times. Store the sum of the numbers rolled in each roll into an array, and then use this array to print a bar graph (similar to the bar graph in the Programming Example Data Comparison, Chapter 6). Test run your program using 4, 5, and 6 dice and the number of rolls 2500, 3000, and 5000. What type of curve does the shape of your bar graph resemble?
