COMP 122
Week 6 iLab
You are to design a program that will allow some number of grades (up to a max of 100) to be
input by the user. After the data has been collected, your program should calculate and output
the mean and median of the collected data, as well as the sorted grade information.
Design Constraints
Use an integer constant of 100 to specify the number of elements in the array you will use to
collect the grade information. Do not use any global variables in your program. Declare any
arrays you need in your main function and pass the arrays as needed into the functions
described below. The main function is the only function permitted to do any output to the
console!!! Do not do cout operations inside of any other function. Your data collection loop in
your main function must allow the user to enter less than 100 grades. It must also make sure
that the user does not try to enter more than 100 grades. Each data value entered should be
checked to make sure it is between 0 and 100. Any other value entered should be considered
invalid and ignored (ie. not counted as a valid input and not stored in an array). Once the data is
collected, the array and the number of grades collected must be passed to a function called
mean. The mean function must loop through the values in the array, summing them together.
The result of the function is the sum divided by the number of grades collected. The result must
be returned from the mean function to the main function, where is it output in an appropriate
manner (two digits after the decimal point). The main function should then pass the array and
the number of grades collected to the median function. The median of a set of numbers is the
number in the set where half the numbers are above it and half the numbers are below it. In
