1.This is an extension to an earlier lab involving a grade reporting system. Write a program that prompts the user to enter the number of students and the number of grades per student. Then
i.Dynamically allocate the space for the two dimensional double array
ii.compute the average, maximum and minimum of each set of student grades
iii.compute the average, maximum and minimum of all the values
iv.report the results
You will need a driver that continuously re-prompts the user for new sets of data. You must modify the functions you wrote in an earlier lab to compute the average of an input array of doubles and the one to compute the maximum and minimum. Recall that the original average function accepted the array as input parameter and returned a double that is the average. The max/min function had a return type of class MaxMin which contained the calculated maximum and minimum grade. It accepted the one dimensional array as input parameter. Since you are now tasked to compute the average, maximum and minimum of the entire class, you must write an additional average and max/min method that can accept as input a two dimensional array of doubles. Any other aspects of the new methods remain as is. The basic average, maximum and minimum finding algorithms are essentially unchanged, except that all work is done inside nested loops instead of a single loop. The driver calls the proper functions with the correct parameters for average, maximum and minimum calculations and is responsible for displaying results. I/O function calls should only appear in the driver.
Keep in mind these other general rules of good program construction:
i.Use static final constants to represent the key parameters of the problem.
ii.Use final to ensure that the compiler guards against changes being made to constants and/or method arguments that should remain immutable.
iii.All constants, variables and functions should have names that describe their intent.
iv.Write efficient functions, that is, functions that require as little memory and operations as possible and are general enough for a wide variety of uses.
v.Add comments and good formatting for readability.
Your output should faithfully reproduce all of formatting nuances shown in the sample output below; however, be sure to test your application with different values.
