Using VB.NET write a program that can calculate the grade of a student based on his or her marks in five subjects as input according to the following rules:
Grade A: For average between 100 and 80 (inclusive)
Grade B: For average between 79 and 65 (inclusive)
Grade C: For average between 64 and 40 (inclusive)

I'm working on a function to return a exponential average and there are a lot of examples of exponential moving averages but they all start with a moving average that is just the mean as a lead in to calculating the continuing moving average. I needed just a exponential average of a value set. After Googling my Bing off I still haven't seen anything so here is my attempt at a basic exponential average. Is this correct? Are there any errors? I have seen some text about adding a smoothing value to change the curve of the exponential average but not how that would be implemented.

I put comments on the average output since I kept getting error messages about that. My out keeps saying:
Maximum value: 33
Minimum value: 33
what am I doing wrong?

It works up to this point but when I try to add so that 70-79 is a C, 60-69 is a D, and 60 and less is a F I run in to problems.

Write a program that reads in a set of grades for a class.The program takes in the number of students in the class from the user. When the Get Grades button is clicked the program then reads in a grade (0-100) for each student using an inputbox. The program should then display the percentage of students who pass and the percentage of students who fail.The program should call a function to calculate the average grade for the class. Then finally the result is then displayed.

I am taking an online class and I am having trouble getting my solution to work. My assignment is as follows: In the function, declare variables for the average score and the letter grade. Calculate the average, use If/ElseIf statements to determine the letter grade, and return the letter grade.
Create a subprocedure for the Click event for the btnDisplay button. It should call the CalculateGrade function with three arguments (the three test scores from the text boxes), and display the returned value in the lblGrade box.I have looked all over the internet and have had no luck finding an example to look at I am taking an online class and I am having trouble getting my solution to work.

"I need to create a program that will allow the user to enter in 10 test grades from a class. I need to store these grades into an array, and use a loop to add up the total. Then I'll need to output the average, and the letter grade for the average using:

80 - 89 B
70 - 79 C
60 - 69 D

That's all it needs to do. Here is some code that shows you that the only thing I know how to do is (allow the user to enter in 10 test grades from a class.) The rest I'm so lost on and have a crappy instructor. This assignment is due tomorrow, but the instructor is not available over the weekend.

here is my problem. i have to enter two grades, each grade should be an integer between 0 and 100 inclusive. Calculate the average of the two grades. If the average is greater than or equal to 90, display "Grade is an A!". It goes down the line for "if average is _______, display " ______is a/n __!" I get the last part and I know how to figure an average...but i am not sure how to type it in code. He did an elseif example, but it wasn't with 2 numbers and didn't have to average anything. So I don't know how to write that code....is there anywhere to look to find it? Here is what I have so far.............

The idea of this program is to calculate and find total and average for 3 Students automatically. That is when the first data is entered and click on button the total and average of first student should be displayed in listbox. And we should be able to enter second data. Bu the problem is it is just printing the first average and total thrice.
Dim a As String
Dim tot, avg, N As Single
Dim I As Integer
For I = 1 To 3
tot = Val(TextBox2.Text) + Val(TextBox3.Text) + Val(TextBox4.Text) + Val(TextBox5.Text) + Val(TextBox6.Text)

need to make sure I got everything right for my Calculate Button in displaying the Total and Average.

My problem is mostly in the Calculate Button, what is CStr? I already used that because I set my Explicit On and that suggested it. Also when I debug I enter my 3 grades and click calculate, 0 is displayed in both my Total and Average Label box.For the Average, how would I display it to 2 decimal places?How would I set a parameter for the exam scores to be between 0-100?Would it be Try/Catch? And where would I place that coding?How do I convert my textboxes to integers?

I'm having a problem creating a function for calculating an average. I need to divide the sum of a column of integers by the number of rows in that column. These integers are generated by a datediff command and their values are assigned to textboxes in a report. The results can only be whole numbers, no decimal points.
I'm pretty new to this so if this is an obvious question please excuse my ignorance. If you need any more information to address my question please let me know.

OK, so I've been given an assignment due for Monday, which was to create a console program which allows the user to enter an unknown quantity of numbers, then have the Mean, Median and Mode averages displayed of said group of numbers.
So far I've managed to get the Mean and Median to work, for both odd and even quantities of variables. I am however stuck on getting it to calculate the modal average! I don't really know how to approach this, would a structure with two fields, variable and quantity of variable, work?
Below is the code, I haven't made it display discrete of continuous data yet, I'm leaving that for the end.

I'm trying to calculate the rolling average in a crystal report. I have got 4 weeks in a month, and I have calculated the average for each week so long. Now I want to calculate a rolling average. eg:
For week1: rolling average = (week1Average)/1
For week2: rolling average = (week1Average + week2Average)/2
For week3: rolling average = (week1Average + week2Average + week3Average)/3
etc.
The problem with the code below is that, it is not looping through,therefore the rolling average for each week is the same as its average value wich is not correct.
Dim i, weekNum as number
Dim tot as double
weekNum =Distinctcount({ItemRating.WeekNo})

I wrote the following generic LINQ extension for calculating weighted average in Visual Basic 2010:
<Extension()>
Function WeightedAverage(Of T)(ByVal source As IEnumerable(Of T),
ByVal selectorValue As Func(Of T, Integer),
ByVal selectorWeight As Func(Of T, Integer)) As Double
Dim weightedValueSum As Double
Dim weightSum As Integer
[Code] .....
How can I call this function as an Aggregate function of another LINQ query? I tried it in the following way:
Dim q1 = From jd In oContext.JobDatas
Where jd.Year = 2011
Select jd
Dim q2 = Aggregate num In q1 Into WeightedAverage(num.AvSalary, num.NumPosHolder)
The Visual Basic 2010 editor is telling me that the second query (q2) of the following code is not valid statement. On the comma between the first an second argument it's saying: ")" required.
I want to include an average in a column where the average ignores zero values in a report cell where the column may have
17
19
0
[code].....
I want 16, not 11 so (17 + 19 + 12 + 13 + 19) / 5 not (17 + 19 + 0 + 0 + 12 + 13 + 19) / 7 Something like this if it would work.
=SUM(Fields!fieldname.Value) / Count(iif(Fields!count_cycle_per_hour.Value >= 0,Fields!fieldname.Value,0))
Essentially just average everything in the column NOT a zero?
I'm in a computer science class, and we are writing simple programs using Visual Basic 2008. I am really inept when it comes to this, as I have never done it before. I need to write a program that: "Asks the user for 5 numbers and computes the average. It then displays the average with an appropriate message before the average."
I have been really close with this, but I can't get the numbers to add up, then divide by 5, and display a pop up message.
I am in a visual basics 2008 class for my MIS degree. This is the beginners class. We were instructed to build a program that calculates a score average. However, we get extra credit if we figure out how to drop the lowest test score. I do not know how to do this. The teacher won't help with the extra credit. I will post my code.

I have a homework assignment to code an application that allows the Prof to display a grade based on the numnber of points he enter. The grading scale is : 0-299 -F; 300-349- D; 350-399- C; 400-449- B; 450-500- A. We are to store the minimum points in a 5 element one dimensional Integer array name intPonts and store the grades in a 5 element one dimensional String array name strGrades. The arrays should be parallel arrays. The procedure should search the intPoints array for the number of points entered by the user and then display the corresponding grade from the strGrades array.
I have stored the minimum points and grades in a one dimensional integer and string array respectively. I have coded the program, and when I put in random points, it gives me the letter grade. For example, if I put in 376 it will display a "C"; if I put in 200, it will display an "F". However, if I put in anything over 449, it will NOT display an "A", it just leaves the lbl blank. I am stumped on how to get the code to read pass 449 points.

Write a program to analyze a list of grades to determine the number of A's, B's, C's, etc. after applying a curve percentage selected by the user. When the form loads it should contain all the grades and available curves in the list boxes on the left. The user selects a curve and clicks the "Apply Curve" button. The program should display the curved grades (based upon the selected curve) and the grade distribution in the list boxes on the right?
View 1 RepliesI'm trying to code a program that averages a grade from a list box, but the numbers in the second list box could change, so not sure how to code that.

Microsoft is trying to assure that it loves VB and VB programmers and wants them but in reality the opposite is happening. All code samples either from Microsoft or third party developrs portrait C# code. For the same reason C# programmers are challenging VB Programmers in every field.
View 5 RepliesI am trying to make a simple program that utilizes lists, loops, arrays, and multiple forms. I started the program in which I have incorporated lists and loops already.A summary of my program; I am trying to be able to add a name to a combobox list, and assign a grade to that particular person (grade of A = 4, b = 3, ect ect). I am assuming I should utilize the array concept at this point when assigning the grade to the name, but I am not exactly sure what to do. I have attached a screen shot of my form, and I will post what code I do have so far.Also, when all the grades are entered with their corresponding names, I want to also have a summary screen pop-up with the names and which grades they received, plus the average.[code]
