Write a program that simulates the rolling of two dice. The program should use rand to roll the first dice and should use rand again to roll the second dice. The sum of the two values should then be calculated. Note: Since each dice can show an integer value from 1 to 6, then the sum of the to values will vary from 2 to 12, with 7 being the most frequent sum and 2 and 12 being the least frequent sums. Below shows the 36 possible combinations of the two dice. Your program should roll the two dice 36,000 times. Use a single-subscripted array to tally the numbers of times each possible sum appears. Print the results in a tabular format. Also, determine if the totals reasonable (i.e. there are six ways to roll a 7, so approximately one sixth of all the rolls should be 7).
Write a program that simulates the rolling of two dice. The program should use rand twice to roll the first
die and second die, respectively. The sum of the two values should then be calculated. [Note: Because
each die can show an integer value from 1 to 6, then the sum of the two values will vary from 2 to 12, with
7 being the most frequent sum and 2 and 12 the least frequent sums.] Figure below shows the 36
possible combinations of the two dice. Your program should roll the two dice 36,000 times. Use a one-
dimensional array to tally the numbers of times each possible sum appears. Print the results in a tabular
format. Also, determine if the totals are reasonable; i.e., there are six ways to roll a 7, so approximately
one-sixth of all the rolls should be 7.

Write a program that asks for the names of three runners and the time it took each of them to finish a race. The program should display who came in first, second, and third place. Think about how many test cases are needed to verify that your problem works correctly. (That is, how many different finish orders are possible?)
Input Validation: Only allow the program to accept positive numbers for the times.

In many businesses across the country, people are buying food and goods using cash. Whenever a purchase is made with cash, it is usual that change must be back to the customer. Business point of sales software help to ensure that the correct change is return to a customer by providing detailed information of the change that should be returned to the customer. using the fewest number of bills and coins. In this assignment, you are asked to design and implement a program that writes out what bills (ones, fives, tens, twenties) and coins (pennies, nickels, dimes, and quarters) that should be returned to the customer given two inputs from the user: A total cost of a sale. The amount that was paid by the customer. Ensure that your output is grammatically correct.
