Using a Two Dimensional array, produce the speeding fines report including the speeding fines
statistics. The speeding fines statistics must display the highest and lowest speeding fines in the
two dimensional array.

Modify Program Sample-1 by applying a structure array in the program. The program should accept 5 records of books and displays them on the screen.
The program should also include two functions: (1) a function for entering book information; and (2) a function for displaying the records.

Using a Two-Dimensional array, produce the vehicle type sales report and the total sales made for
each vehicle type. If the total sales made per month are greater than or equal to 100, gold status
is awarded. If the monthly sales are less than 100, silver status is awarded.

print(i[0])
#loop through displayList
for i in range(0,len(displayList)):
#Test if the fist item in the current sub-list contains the text "Price Level
#Tip: Remeber that each sub-list is a (displayList). So you have
# to access its items via displayList followed by TWO indexes.

#Extract the second item from the currnet sub-list into variable called priceLevel
priceLevel = ...
#Test if priceLevel is between previousPrice and currentPrice OR
# priceLevel == previousPrice OR

...each module. Make use of an abstract class named Student that contains variables to store the
student number, test result, assignment result and exam. Create a constructor that accepts the
student number, test result, assignment result and the exam result as parameters and create get
methods for the variables. The Student class must implement an iReport interface that contains the
following:
public interface iReport {
public void print_report();
}
Create a subclass called Student_Report that extends the Student class. The Student_Report class
must contain a constructor to accept the student number, test, assignment and exam results as
parameters. Write code for the print_report method which calculates each assessment weighting as
follows:
Assessment Weighting
Test 25%
Assignment 25%
Exam 50%
Finally write a useStudent class to instantiate the Student_Report class
from January to March 2018. The rows and columns represent the monthly sales of each device.

Write a program that will prompt the user to input the following:
1. The number of dice to be rolled.
2. How many times the dice should be rolled?
Since the values above will vary, you must use pointer arrays and dynamically allocate memory.
The program will store the total of faces per roll and the values will be later used to plot a graph. The graph should look like the output shown below

The asterisk (*) tallies the number of times that total has occurred. 3 and 18 are the minimum and maximum totals, respectively, for rolling 3 dice.
The declaration and implementation sections of the class have been defined for you. Use it to complete your program.
