Declare Variables For The Average Score And The Letter Grade?
Apr 18, 2011
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. My assignment is as follows:

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.
Module Module1
Dim Average As Integer = 0
Dim Response As String = ""

"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:
90 - 100 A
80 - 89 B
70 - 79 C
60 - 69 D
Below 60 F"
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.

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)

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.
Public Function GetPassRate(ByVal intGrade As Integer) As String
Do Until gradeCounter >= NumericUpDown1.Text
If intGrade >= 40 Then[code].......

I made an application that calculates course grades. The program runs perfectly except for the last part
The the final grade number comes from the label "lblCoursePts" and i want to put the letter grade in the label "lblFInalGrade" Here is what i have.
'Determine the final letter grade
Select Case lblCoursePts.Text
Case 90 To 100 : lblFinalGrade.Text = "A"

How do you enter in a code for an overall letter grade from a percentage given? I have a seperate box for the letter grade and a seperate one for a the percentage grade . I have it setup when an overall grade and possible grade is entered into boxes it will give me a grade percent but not a letter grade. How is that added? I am doing this for my course project but dont undersatnd the coding very well. I am just trying to pass the class.

I need someone with patience and can go through a solution with me from the Clearly Visual Basic book. I'm good with computers and can usually learn things relatively fast on my own time and in my own way, but I'm going to school for computer programming and, with certain things, I learn better with things explained to me rather than reading from a book. If someone has the time to go over this solution I'm doing and explain it to me in a way I'd have a better chance of understanding, I'd be truly grateful. I need a tutor, for lack of a better word. The lab I'm doing is from the Clearly Visual Basic book and the instructions are:
Code an application that displays a letter grade based on the averages of three test scores. Code the application using a function to determine and return the letter grade. If the average is at least 90, the grade is A. If the average is at least 80 but less than 90, the grade is B. If the average is at least 70 but less than 80 the grade is C. If the average is at least 60 but less than 70, the grade is D. If the average is below 60, the grade is F.

I have been struggling with my programming class from day one. I still can't seem to grasp the complete logic on how to write code. Anyhow, I have an assignment due that I am stuck on. Here is the assignment:
In this exercise, you code an application that displays a letter grade based on the average of three test scores. Open the Grade Solution (Grade Solution.sln) file, which is contained in the ClearlyVB Chapl8Grade Solution folder. Code the application,using a function to determine and return the letter grade. If the average is at least 90, the grade is A. If the average is at least 80 but less than 90, the grade is B.If the average is at least 70 but less than 80, the grade is C. Tf the average is at least
60 but less than 70, the grade is D. If the average is below 60, the grade is F.
You will be developing the code for the function on your own. Below the Public Class frmMain line, insert this function header:Private Function CalculateGrade(ByVal testScore1 As Decimal, ByVal testScore2 As Decimal, ByVal testscore3 As Decimal) As String
In the function, declare variables for the average score and the letter grade. Calculate the average, use IF/Elself 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.

The exercise prior to this one had us use two parallel arrays that store a letter grade (A, B, C, D, F) and the minimum points needed for each grade. The user input the points earned by the student and the program shows their letter grade. It took a minute, but I got that one done, and it does what it's supposed to do.This exercise has us modify that exercise to ask for the (via InputBox in MainForm Load event) total points possible. The grade is then determined by percentage of the total points possible. For instance, if x is the user input, an "A" would be 90% of x.

It is meant to average 15 user-input grades and then from there I have to provide the letter grade that corresponds with the average percent. I understand how to provide the corresponding letter grade, but I don't understand how to get the average. I've tried putting it into arraylist format

Is it at all possible to declare variables dynamically? Something like Dim Answers & i As ArrayList. What I'm trying to achieve is putting one or more answers to a question into an array. Or should I really be looking at a mult-dimensional array to store the question number and answer? How would I add to and access a multi-dimentional array?

What happens if I do: Dim x As New Int32? Is a object of int placed on the heap? If it is, maybe your application would be able to access global variables faster if they were reference types.
A global variable as an value type should be somewhere at the bottom of the stack most of the time and it might take more time to get to this then to get a object from the heap. Unless it's the same story with the pointer of this object is also at the bottom of the stack of course.

I put "isolated context" in quotes because I don't know what else you would call it. Basically, in C#, you can do this:
{ int i = 0; }
{ int i = 1; }
The curly braces create an isolated context which allows you to declare two variables with the same name in the same method or property logic. Is this possible in VB.NET? Also, what do you call this aside from an isolated context?

I am writing a noughts and crosses game and I want to be able to keep score everytime each character wins a game, I have written a sub routine to handle this but it seems to count up in 5's and 10's??I have used a global variable like this Dim i As Integer = 1 then declaired that variable in my sub like this i += 1 (I thaught that this would just add 1 everytime X won a game)then used the variable i to add the score to the label control that keeps the score for the character X.My question is, am I using the correct syntax (+=) for the variable.
