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
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
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
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 order to find the
median, this function will need to sort the original data. The simplest sorting
procedure is called bubble sorting. The following pseudocode describes bubble
sorting for X valid array elements.
for ; outer < x;="" outer++="">
for ; inner < x-1;="" inner++="">
if array[inner] > array[inner+1]
After the data has been sorted, the median value can be found. If the array has an odd
number of elements the median is the value of the middle element (Hint: arraySize/2
is the middle element). If the array has an even number of elements then the median
is the average of the middle two elements (Hint: arraySize/2 and ( arraySize/2) - 1
are the two middle elements). The median value should be returned by the median
function. The main routine should output the median value in an appropriate
manner. The main routine should also output the sorted array with 5 grades per line.
Carefully develop test cases for your program. Most of your test cases do not need to
contain lots of values. Make sure to include incorrect inputs such as negative grade
values. Calculate what your mean and median values should be for your test cases.
Document your test cases in a Word document. Run your test cases with your
program to see if your program generates the expected output. If not, troubleshoot
your program and fix the problem. When your program executes a test case
correctly, take a screen shot of the program output and paste it into your Word
document to prove that your test case executed correctly with your program. Make
sure that your code is properly formatted! You also need to make sure you include a
comment block for each function which documents the purpose, inputs, and outputs
of each function!
Create a program using Visual C++.Net. Make sure to capture a screen shot of your
program running your test cases! The best way to do this is to click on the console
window you want to capture and then press the Alt and PrintScreen keys at the same
time. Then paste your captured screen image into your Word document. Your Word
document should contain your test cases, the screen shots doc
